Diego Costa is likely to sign with Tianjin Quanjian on a transfer worth up to £76 million ($99 million) for Chelsea.

Costa has been a talented but sometimes difficult player during his three seasons with Chelsea.

According to sources close to Costa, no deal has been signed yet with Tianjin Quanjian.

Antonio Conte is happy with Costa's focus despite the transfer speculation.

“I repeat the same concept about Diego and every single player,” he said. “But I’m not worried [about his focus]. I see my players every day and I can see the right concentration, the right focus, about my players. I think in this part of the season you arrive with four games to go and have the possibility to reach a fantastic target for us – don’t forget we started this season with a lot of problems and now we have a fantastic possibility to reach a great target and win the Premier League and also to play the FA Cup final, another great competition... these two big targets for us are very, very important. They are the most important things for us. Speculation or news, for me, is not important.

“I don’t know about this [potential deal to take Costa to China]. Now it’s very important for every single player and person who works for Chelsea to be focused on the present, because the present is more important for us than the future. But I’m not worried about this. I see my players every day and I see the right concentration and focus in them.”
