Chelsea’s pursuit of Diego Costa hasn’t been without its difficulties and now the club are trying to push through the deal as quickly as possible with fears that Atletico Madrid are waiting to see if any other offers will be made by rival clubs.
Costa completed his medical on Wednesday ahead of his £32million switch to West London but formalities are still not finished and now Chelsea are worried that the Spanish champions are holding back to see if a more lucrative deal can be made elsewhere.
The Blues met Costa’s buyout clause and the player has told the club he wants to leave with both parties eager to complete the deal before the World Cup gets underway, something that should be straight forward given that only standard paperwork is left to do.
But, the deal, worth a reported £150,000 a week, is still not finalised which is of cause for concern for Chelsea.
Chelsea: Potential summer transfer targets
Chelsea: Potential summer transfer targets
1/9 Paul Pogba
Former Manchester United midfielder was spotted in west London setting the rumour mill into overdrive. The classy French midfielder, still just 21, impressed at the World Cup and has been linked with a blockbuster £60m move to Stamford Bridge, despite the recent arrival of Cesc Fabregas. However, he is also linked with a move to Manchester City as a potential replacement for Yaya Toure.
2/9 Adrien Rabiot
The talented teen put clubs in Europe on alert after rejecting a contract offer from Paris Saint-Germain. Chelsea made a move for the Frenchman in January and have gone back in for him, even though he is highly rated by PSG coach Laurent Blanc.
3/9 Sami Khedira
The German midfielder missed five months for Real Madrid's season with a knee injury and has played just 15 games this term. With Madrid reportedly interested in signing new players in central midfield, Khedira's future at the Bernabeu could be at an end. The 27-year-old is interesting Arsenal, but should Chelsea go in for him too, they would be getting a player that Mourinho knows well and real quality in front of the back four, not dissimilar to club legend Claude Makelele.
4/9 Yaya Toure
An outside bet, of course, but with all the drama surrounding the Toure and Manchester City recently, Chelsea could swoop. A powerhouse of a midfielder with a surprisingly deft touch and devastating skill at the dead ball, the 31-year-old would be huge assent to any team in the world. Toure cost City £24million in 2010, so any offer would have to huge from Chelsea if they are to persuade the Sky Blues to sell to a title rival.
Tottenham's summer signing hasn't quite lived up to the form he reached in Brazil's Confederations Cup victory in 2013 and struggled at the World Cup, but he has still performed well enough to have Chelsea and Real Madrid reportedly interested in acquiring his services. The 25-year-old would fit in well at Stamford Bridge given the Blues' strong Brazilian contingent already. Paulinho had a mixed first season in the Premier League, scored six goals with three assists last season and not the return Spurs were hoping for, and the lure of Champions League football could persuade the midfielder to switch London clubs.
6/9 Fabio Coentrao
With Ashley Cole having joined Roma and Ryan Bertrand also likely to leave, Jose Mourinho will be in need of a quality, experienced left-back and one possibility is Real Madrid's Coentrao. The 26-year-old came close to joining Manchester United in January and is likely to lose his starting place at Madrid when Marcelo is fully fit again next season. Carlo Ancelotti denies any rumours that the Portuguese defender will leave but if the right offer were to be made by Chelsea, he could be on his way to London and nail down a starting role with ease.
7/9 Edinson Cavani
After a season of playing in the shadow of Zlatan Ibrahimovic at PSG, Cavani looks likely to leave the French side after just one year and become the main man at an English club next season. Chelsea remain interested in the Uruguayan but Chelsea are despite a deal for Diego Costa already complete, but may face competition from Manchester United. The 27-year-old cost PSG €64.5million last summer, so any offer from Mourinho would take a large slice of his funds but with his striking power and goals an almost guarantee, it could be a risk worth going for.
8/9 Radamel Falcao
The Colombian striker did not regain fitness in time for the World Cup but it has given him a good chance to weigh up his future. Seemingly always in transfer rumours despite his €60m switch to Monaco last summer, Falcao is a long-term target of the Blues, though Diego Costa has filled the previously vacant No 9 role. The 28-year-old lit up La Liga during his two seasons with Atlectico Madrid but, mainly because of injury, has failed to live up to his price tag in France. If unrest reports are true, Chelsea could attempt an offer.
9/9 Raphael Varane
Reportedly unhappy at Real Madrid due to his low wages in comparison to his team-mates, the centre back has been linked with a move away. Chelsea are reportedly one of the clubs interested in the France international with Jose Mourinho seeing him as a long-term replacement for John Terry.
A Chelsea source said: "Chelsea have made an offer to Atletico Madrid in compliance with the buyout terms in Diego Costa’s contract, and Chelsea have been advised that the player has provided notice to Atletico Madrid invoking the buyout clause and directing the club to accept Chelsea’s offer.
"Chelsea looks forward to entering into formal transfer documentation with Atletico Madrid as soon as possible so that the player can concentrate on the World Cup."
Chelsea and Costa will be hoping that the deal has been completed in time for Spain’s opening World Cup game against the Netherlands on June 13.
