However, Costa will not bow to pressure to clean up his act and will continue to play the way that has netted him 17 Premier League goals for the Blues so far this season.
"I'm not going to change my way of playing," said Costa ahead of Sunday's Capital One Cup final against Tottenham
"I know I have to be a little bit more careful because it's not the same when I do something, and when someone else does it. Something I do, it's talked about much more than another player.
"I have to be extra careful, but I'm never going to change the way I play. That's what got me here, that's the way I play."
He added: "I'm not angry about the ban. It's gone," he said. "I still don't even know why it happened, but it happened. Now I'm just trying to get back to my best physical form. You have to forget it.
"Now, I'm running a little bit behind after the suspension, trying to do my best, working hard and hopefully I'll be 100 per cent."
