He was unrepentant on Tuesday as he stood by his decision while Arsenal midfielder Aaron Ramsey claimed he was 'over' the tackle by Stoke City's defender two years ago which had placed his career in jeopardy due to a double fracture.
Coleman said: "The bottom line is that we want to go to Brazil. How are we going to do that?
"Well, we need the best players we can possibly get our hands on. We need the best players and the strongest squad.
"Ryan is a Premier League centre-back and has been for two or three seasons in the toughest league in the world.
"I've not had a conversation with Ryan Before I do, I'll have another conversation with Aaron. He handled the first one in a mature manner.
"We know there's an issue there. But you don't have to like each other to play together.
"You have to have an edge. This is a group of men. I don't expect Aaron and Ryan are going to be best mates. As long as they respect each other and work hard for each other on the pitch, that's all that matters."
