Wigan Athletic defender Gary Caldwell is enjoying his time at the DW.
Caldwell believes he has become a better player since moving south in January, 2010, not least because he is asked to do more defending with Wigan.
"I think the Premier League tests you every week," he said.
"The players are physical and the standard is very high so you have to raise your game and adapt to that.
"At Celtic you were more of a centre half that had to create and start play and didn't defend as much.
"At Wigan, at times you are playing Manchester United and Chelsea where you are under the cosh and you have to defend and learn how to deal with that pressure.
"Throughout your career you have different experiences and challenges and that's what brings you on as a footballer."
