Manchester United defender Jonny Evans has no problem competing with Phil Jones and Chris Smalling for a centre-half spot.
Evans is not fazed by the challenge.
Now 23, the Belfast-born player has been around long enough to know battles always have to be fought at a club the size of United.
"I have always thought that being at a club like Manchester United, if you can't accept a challenge of someone wanting your spot, you don't deserve to be here," he said ahead of their United States tour opener against the New England Revolution in Boston.
"That is what Manchester United is all about. You are constantly being tested.
"It is down to you, whether you are good enough, or whether you are putting the effort in to play for the first team."
