Howard Webb became the first English referee to use the vanishing spray that has taken this World Cup by storm.
Webb, taking charge of Colombia and Ivory Coast's Group C clash, started trending on Twitter after using the spray for the first time.
Most of the posts tended to be jokes about Webb's lack of hair and the resemblance of the spray to shaving foam.
However, despite the praise the spray has received at the tournament, it will not be introduced in the Premier League next season, and the Football League is yet to comment. It will be used in the Champions League next season.
The Premier League announced on Wednesday it will monitor the sprays effectiveness before introducing it.
Show all 15 1 /15The most controversial and shocking moments of the World Cup so far The most controversial and shocking moments of the World Cup so far Yuichi Nishimura gives Fred a penalty The opening game of the World Cup between Brazil and Croatia was meant to be all about the hosts, but it was Japanese referee Yuichi Nishimura who stole the show. With the scores level at 1-1 and Croatia looking as likely to take the lead as the team in yellow, Nishimura gave an incredibly soft penalty after minimal contact between Dejan Lovren and Fred. Neymar, who perhaps should have been sent off earlier in the game for an elbow on Luka Modric, stepped up to score his second of the match and Brazil eventually won the match 3-1.

The most controversial and shocking moments of the World Cup so far Finally, justice for Mexico Mexico completely outplayed a poor Cameroon side but only after not one but two disallowed goals for Giovani Dos Santos. The former Tottenham striker had a volley and a header disallowed despite replays suggesting both should have stood. Thankfully Oribe Peralta scored during the second half and Mexico won the match.

The most controversial and shocking moments of the World Cup so far The pantomime villain The 5-1 defeat inflicted on Spain by the Netherlands was perhaps shocking enough, but the greatest moment of controversy came when pantomime villain Diego Costa appeared to aim a head-butt at Bruno Martins Indi. Being booed throughout by the locals due to his switching nationality, the soon-to-be Chelsea striker appeared to move his head towards the Netherlands player.

The most controversial and shocking moments of the World Cup so far Hart goes mental at ball boy Perhaps angered at being completely duped by an Andrea Pirlo free-kick that thankfully for England hit the bar, or maybe just desperate to get the game going again, Hart went wild as he looked to retrieve the ball. The Manchester City goalkeeper screamed and swore at the poor ball boy behind the goal.

The most controversial and shocking moments of the World Cup so far Just because your losing A superb performance by Joel Campbell not only earned Costa Rica a win against Uruguay, it also saw him given a good kick by Maximiliano Pereira.

The most controversial and shocking moments of the World Cup so far Play on Thanks to the referee, this was a moment of controversy avoided. With the scores level at 1-1, Ecuador had a great chance to take the lead in injury time. But after a superb defensive block by Valon Behrami, the Swiss broke. A dreadful challenge went in but referee Ravshan Irmatov waved play on and seconds later there were jubilant scenes as substitute Haris Seferovic rifled into the net.

The most controversial and shocking moments of the World Cup so far Goal line technology Making its first appearance at a World Cup, Fifa have been making the most of the goal line technology at their disposal. Goals that have clearly crossed the line have been replayed in great detail, just to confirm they have. But during France's win over Honduras the technology caused confusion, particularly for BBC commentator Jonathan Pearce. Karim Benzema's initial shot was shown not to be a goal, but when the cameras were rolled forward, it was shown that goalkeeper Noel Valladares had nudged the ball over the line. Quite simply it was a goal, but it still left a few people perplexed, particularly the former Robot Wars commentator.

The most controversial and shocking moments of the World Cup so far Broken nose Clint Dempsey has always been something of a hard man. The USA forward once told of how he tried to punch a teacher. But it seems the former Fulham man can take it as well as dish it out. After putting his team into an early lead against Ghana, the Stars and Stripes captain broke his nose after a collision with John Boye. He played on.

The most controversial and shocking moments of the World Cup so far Pepe plonker Pepe has never professed to be a mildly mannered defender, but even his actions against Germany were shocking. A coming together with Thomas Mueller saw the Germany striker making the most of the situation, going down rather dramatically. Angered by this, the Portugal defender decided to make sure there really was some damage done by pushing his head towards the Bayern Munich midfielder. It led to a straight red card and contributed to Portugal being mauled 4-0. To rub salt in Pepe's wounds, Mueller scored a hat-trick.

The most controversial and shocking moments of the World Cup so far Deja vu for Capello Fabio Capello could have been forgiven for thinking he'd see it all before during Russia's first game. The match with South Korea ended 1-1 and involved an horrendous goalkeeping mistake by Igor Akinfeev, bringing back echoes of England's opener against the United States four years ago in which Rob Green let the ball trickle into his net.

The most controversial and shocking moments of the World Cup so far Marcelo dive Perhaps encouraged by the refereeing mistakes in Brazil's favour against Croatia, when the hosts were struggling to break down Mexico, Marcelo took a theatrical dive in the box. It was the worst bit of simulation this World Cup had seen, and thankfully the referee agreed.

The most controversial and shocking moments of the World Cup so far Really disgusting Cameroon The actions of Alex Song and Benoit Assou-Ekotto were labelled 'really disgusting' by their own coach after Cameroon's 4-0 defeat to Croatia. Song was sent off for a shocking elbow on Mario Mandzukic, but things really descended into chaos when Assou-Ekotto became involved in an on-pitch argument... with his own team-mate!

The most controversial and shocking moments of the World Cup so far The end of the Spanish reign Having won the last World Cup and the European Championships either side of it, the end of Spain's dominance came in shocking style. Having been whipped 5-1 by the Netherlands, a result was needed against Chile. But the tiki-taka that once mesmerised audiences looked flat and uninspired. Chile won the game 2-0 and Spain's defence of their crown was over before it really got going.

The most controversial and shocking moments of the World Cup so far Luis Suarez bites again The Uruguayan striker has been built up as one of the most lethal finishers at the World Cup, and rightly so, but he shocked the world when he appeared to bite Italy's Giorgio Chiellini during the 1-0 victory over Italy. It was the third time Suarez had been involved in such an incident, having previously been found guilty of biting PSV Eindhoven’s Otman Bakkal and Branislav Ivanovic of Chelsea in recent years.

The most controversial and shocking moments of the World Cup so far Beam me up Fabio Igor Akinfeev makes his second appearance here but on this occasion it wasn't his fault. According to Fabio Capello, the Russian goalkeeper was blinded by a laser beam shone in his eyes from someone in the crowd during the build-up to Algeria's equaliser in their 1-1 game. It was a result that saw Russia exit the World Cup.

Officials do not think encroachment or moving the ball is a significant problem.
or fans of South American football, the foam spray is nothing new, having been used in league matches on the continent for some years, but for the huge global audience, these are bold new days.
No more can the defensive wall creep forward, cramping the free kick taker's style, when the referee's back is turned and in theory we should now see more goals scored from free kicks.
But what is the magic disappearing foam made of? According to LiveScience it is: “a mixture of butane, isobutane and propane gas; a foaming agent; water; and other chemicals.
The vanishing spray has been a great success at the tournament (Getty Images) "When it leaves the can, the gas depressurises and expands, creating small, water-covered droplets on the field. The butane mixture later evaporates, leaving only water and surfactant residue behind.”
The spray is the brainchild of Argentine journalist Pablo Silva who developed the spray called "9:15 Fairplay," a reference to the metric equivalent of the free-kick distance requirement.
