It will take a massive U-turn to stop Diego Costa moving to Chelsea this summer, according to French newspaper Le 10 Sport.
The Atletico Madrid striker has been in inspirational form for Atletico Madrid this season, scoring 26 goals and only trailing Cristiano Ronaldo in the top scorers charts in La Liga.
His astronomical rise has attracted the interest of a number of Premier League clubs including Chelsea, Arsenal and Manchester United.
However, it is Jose Mourinho who has moved quickly to seal the signature of the Brazilian-born Spanish international. Reports surfaced last week claiming that Mourinho had launched a stunning £40m bid for the striker in an attempt to fend off competition from David Moyes and Arsene Wenger.
Arsenal's interest is reported to have died off in recent weeks as lukewarm scouting reports convinced Wenger to look for other targets. Manchester United were seen as bigger rivals for Costa, as Moyes is set on rebuilding a flailing Manchester United squad that has failed to impress this year.
But Chelsea's quick move, intent on sealing a deal before the World Cup, seems to have done enough to beat their Premier League rivals to Costa's signature.
According to those reports in France only a dramatic turnaround in negotiations can stop the 25-year-old from stepping out at Stamford Bridge in the blue of Chelsea next season.
Not only are Chelsea thought to be very close to agreeing a deal with Atletico but the player is also very keen to work under Mourinho, who still has a big reputation in Spain following his time in charge of Real Madrid.
Mourinho is also set to axe all three of his current first team strikers and may even let Fernando Torres leave on loan if a permanent club can not be found. Samuel Eto'o will not be offered a new deal when his current one expires in the summer while Demba Ba is also deemed surplus to requirements.
The future of Romelu Lukaku is also under some doubt at this moment in time with reports suggesting that Mourinho can not find a place for the Belgian in his squad.
