Chelsea have opened negotiations with Atletico Madrid over the £35m transfer of striker Diego Costa.
Jose Mourinho plans to revamp his failing strikeforce this summer, and wants the Brazil-born Spain international to spearhead his new-look attack from the start of next season, according to the Express. Costa, 25, has been in scintillating form this season, scoring 25 goals in 30 La Liga matches.
His goalscoring exploits have left Atletico with an excellent chance of winning their first La Liga title since 1996, with Diego Simeone's side currently top of the table with seven matches left to play. Meanwhile Mourinho, whose side were beaten 1-0 by Crystal Palace on Saturday, has confirmed he will look to sign a striker when the transfer window re-opens this summer.
"It's clear in everybody that Chelsea next year wants to bring a striker," Mourinho told reporters after Saturday's defeat at Selhurst Park. "It's also clear that we want to improve our players. I can't and I don't need to improve (Branislav) Ivanovic, (Gary) Cahill, John Terry.
"There are other guys I need to improve. I think we are doing that step by step, but it's not enough to be champions."
Mourinho ruled his side out of the title race at the weekend, despite the fact his side find themselves just two points behind league-leaders Liverpool with six matches remaining, but has insisted throughout the season that his side will be in a much stronger position to win the league next season.
With Costa at Stamford Bridge, Mourinho's side would be amongst the frontrunners to win the 2014/15 Premier League campaign.
