Atletico Madrid striker Diego Costa has insisted that he doesn't know why Chelsea fans were cheering from him in the UEFA Champions League first-leg, reports talkSPORT.
The Blues and Atletico played out a 0-0 draw in Spain last week and will go head-to-head in the second leg at Stamford Bridge tomorrow evening.
And, after the final whistle last week, Costa was given a great reception from Chelsea fans, amid reports the Blues are set to make a move for him this summer.
However, Costa has insisted he's happy at the La Liga table-toppers and hasn't paid any attention to the Chelsea fans.
The striker told reporters: "The truth is that I didn't understand anything. I heard my name and asked what they were saying.
"I can't say I paid much attention to it. I'm very happy where I am now."
It remains to be seen as to whether Chelsea step up their interest in the striker, who has been rated at £32 million.
For now though, Chelsea, Costa and Co. will be concentrating on tomorrow's crunch clash at the Bridge.
Chelsea will be looking to secure their place in their third European final in consecutive years with a win against the La Liga outfit.
