There was talk of disillusioned Arsenal supporters bringing black rubbish bags to yesterday's game to illustrate their feelings about the club's current standing. None materialised, although they could always have been offered to Blackburn Rovers' followers. They must be tempted to purloin the idea rather than merely protesting further against their manager Steve Kean, for whom the word beleaguered is no longer adequate.
His team have more than once lost this fixture 6-2, a result surpassed here by Arsenal's biggest victory at the Emirates and Rovers' joint worst Premier League defeat anywhere. They were torn apart down the flanks, notably on the right where Francis Coquelin at full-back and Theo Walcott were excellent. Robin van Persie took advantage of the service to complete a second hat-trick of the season and the precocious Alex Oxlade-Chamberlain added his first League goals.
Rovers lost Gaël Givet to a deserved red card just before half-time for the sort of two-footed tackle that is simply not permissable any more, the only creditable aspect of it being his apologies to the victim Van Persie and the Arsenal manager.The score at that point was already 3-1 and unluckily for Blackburn, the Dutchman was able to continue. Worse, Wenger demonstrated a heartless streak in leaving his captain on the full 90 minutes as well as sending on as substitute a promising loanee called Thierry Henry, who claimed the seventh goal just as the visitors looked capable of lasting out the final half-hour without conceding.
Although Wenger claimed that a dominant performance was more important than a record score, goal difference is important to both clubs in their respective aims at opposite ends of the table. Arsenal doubled theirs in the space of 90 minutes and Blackburn could have done without fellow-strugglers Wolves later beating Queens Park Rangers, their next opponents.
In September Wenger was furious after his team somehow contrived to lose 4-3 at Blackburn in the next away game after the 8-2 humiliation at Old Trafford. Yesterday he exuded bonhomie after a first League win of 2012. "Recently we had quite good performances without always getting the result," he said. "I don't feel we played badly at Fulham or Swansea or in the second half against Manchester United but we couldn't get the result and it affects your belief."
Just as Blackburn start to believe, sometimes scoring three or four goals, they are knocked back again and if they continue to defend like this there will be more trouble ahead. It would seem essential to have the powerful but disenchanted Chris Samba back, though there's no sign of it. "Van Persie is fantastic but the service in to him was too easy," Kean said. "It's the first time this season we've really been turned over and many times after a disappointing result we've always had a reaction. I feel for the fans today because we've let them down."
Givet did so with his reckless lunge at Van Persie, which his manager admitted gave the referee little choice but to dismiss him. Frustration at having conceded two goals in three minutes just beforehand after Blackburn had scored an unlikely equaliser was the only possible excuse. Van Persie had scored the first after only 82 seconds, cleverly drifting behind Scott Dann at the far post to meet Walcott's cross for a tap-in.
It was an entirely unexpected development when Laurent Koscielny clumsily dragged down Anthony Modeste just outside the penalty area, offering Morten Gamst Pedersen the opportunity to curl a delicious free-kick into the top corner of the net.
Only five minutes later after Jason Lowe was forced off injured, a lovelyflowing move right from the back ended with Alex Song finding Walcott, who supplied Van Persie's second goal. In the next attack, Oxlade-Chamberlain scored his first Premier League goal. Strong, quick and clever, he could soon be challenging for Walcott's England place, though Wenger said Fabio Capello has not yet spoken to him, having "other problems at the moment".
Givet's red card meant sacrificing David Dunn, which was hardly ideal. There could have been a fourth for Arsenal before half-time, Thomas Vermaelen clipping the outside of a post, but there was not long to wait. Mikel Arteta drove in from 20 yards, Oxlade-Chamberlain was set up by Walcott and Van Persie converted Coquelin's cross; all this after little more than an hour. Blackburn almost held out without further damage but Henry denied them in the last minute in what is due to be his final home game before returning to New York.
