Keane suggested this week that Carrick's wife is "probably doing the team talk" for his first match in charge, in what was a swipe that comes after controversial comments back in 2014.
Carrick unphased
As reported by The Mirror, Carrick gave the television interview following United's 2-0 defeat to Olympiakos to which Keane said:
"That interview was just like the performance: flat. He should say a bit more, have a bit more urgency, even in the interview," said Keane.
Carrick’s wife Lisa responded on social media, writing: "Roy Keane what a **** will say anything to provoke a reaction."
Speaking this week in his press conference before facing Manchester City on Saturday afternoon, Carrick says Keane’s opinion is irrelevant.
"Honestly, it didn't bother me."
"They're not putting more pressure on me, I don't feel that. I think it's just part of it, I understand the role, there's plenty of opinions around, some are positive, some aren't so much.
"It's totally irrelevant in terms of me and how I go to work and what I focus on. I kind of know already what we want to improve on and how we want to work with the players and I've already said about improving things, there's a lot of opinions, a lot can be said.
“It is the way of the world, I'm not going to pay too much attention to the most of that. It's not for me to do that, I think for me and the players and the staff it's a focus on how we're going to succeed really. That's our job, that's our responsibility, that's what our focus and our minds should be at, is doing what we can for this club."
Carrick will face City this weekend as his side aims to jump into the top four. His focus is on the game ahead and clearly he is ignoring all outside noise, even if it is aimed at his family from a former teammate.
