The 28-year old striker revealed after Chelsea's 2-1 FA Cup final defeat against Arsenal that he is no longer keen on a move to China and that if he leaves Stamford Bridge, it will be to Atleti.
The Spanish striker has been in top form for Chelsea this season and his strong displays for the west London side helped the Blues win the Premier League title.
'I will only sign for another club in Europe, they know that.
Costa, who joined Chelsea from Atletico in 2014, added of his future: "I'm very calm, the only conversation I've had is with the club, for them to call my people to know what's going to happen". If not, I will stay here.
Costa equalised for Chelsea in their FA Cup final defeat.
Atletico could be in the market for a striker this summer, should Antoine Griezmann move to Manchester United, and the Spanish club will have been put on high alert by Costa's comments after the match.
"Everybody knows the club I like".
"If the club really want to sell me, there's only one team for me".
Tianjin also said that they would be drawing up a "rational transfer plan" in order to meet new sustainability demands imposed by the Chinese Football Association in order to curb irrational spending and promote more homegrown talent.
"Money is good, but I'm grateful for what I have right now and I have other things to look forward to, like playing the next World Cup [in Russian Federation in 2018]". We came better for the second half and scored the equalizer, but they went ahead soon after.
