Atletico Madrid have received no official contact from Chelsea for Diego Costa, the club president, Enrique Cerezo, has revealed.
The La Liga hotshot has been heavily linked with Chelsea for a prolonged period of time now and the weight of the rumours stepped up another gear on Wednesday night, after Costa helped Atletico knock Chelsea out of the Champions League.
Indeed, Mourinho has done little to silence the media speculation by going on record to say that he is on the hunt for a striker over the summer and it is thought that Costa is at the top of his list.
However, Cerezo has explained that no official contact has been made from the London club.
"Chelsea? We don't want to know when these games [Atletico’s remaining La Liga fixtures] are so important. We don't want to destabilise the team and we can talk about this later,” he told the Spanish press.
"I can say that there is nothing, not officially, from another club to one of our players. They're not on their way to another team.
"If the question is 'is there a deal for Costa' then we haven't heard anything."
Costa himself has hinted that he knows that there is interest from other clubs in acquiring his services, although he has not specifically stated which ones.
Mourinho’s attacking ranks will also be boosted next season by the return of Romelu Lukaku from his loan-spell with Everton, although the likes of Fernando Torres, Samuel Eto’o and Demba Ba could all leave Stamford Bridge this summer.
