New Birmingham striker Matt Derbyshire insists he will keep his focus against former club Blackburn on Saturday.
Blues boss Alex McLeish has already said the 24-year-old will play some part in the match, his first Premier League game in 20 months after returning to England on a season-long loan from Olympiakos.
But Derbyshire, who moved to Greece in January 2009, insists he will put his emotions aside when he features for the Blues against his old club.
The striker said: "For me, it's more important to put a Birmingham jersey on and go out do the best I can for Birmingham City, whether it's against Blackburn or anybody else.
"I believe I was quite successful at Blackburn in the games I played. I had a fantastic time at Blackburn, it's a nice club, the club I supported as a boy.
"It will be strange, of course, because I know most of the players and they know me but you've got to put it behind you and concentrate on winning the game for Birmingham."
Derbyshire has no regrets about moving to Olympiakos, as he tasted a different league, as well as got to play UEFA Champions League football.
He added: "The first two or three months was quite difficult with the language barrier. You don't know anybody, you don't know the place, you know nothing.
"And trying to learn the Greek language, which is very difficult. But when I got playing and started to do well, everything started to click in place.
"I had a great experience, a great time there. I'd never go back on it. If I had the same time again and it was Olympiakos or Blackburn I would do the same because I got to play Champions League football.
"But I'm delighted I'm back in the Premier League with Birmingham."
