Manchester United head coach Michael Carrick has said the club have moved on from Martinez's post-match comments and insisted the squad are not affected by the fallout.
Carrick said he was "telling the truth" when he described the dressing room as being in a strong place, despite criticism of Martinez from Wayne Rooney, Roy Keane and Gary Neville after the defender's remarks following the 2-0 Champions League defeat by Atletico Madrid.
"There's a lot of people who say a lot of things - ex-pros or not ex-pros - it doesn't necessarily mean they understand what is going on here," Carrick said at his pre-match media conference at United's Carrington training ground.
"Just because people talk on the outside doesn't mean that is the truth. I am telling you the truth. The squad today was in a fantastic place, better than I have seen it for a while. That is it, plain and simple."
Martinez has apologised for the timing of his comments, which focused attention on director of football Jason Wilcox, but not for the words themselves. Carrick confirmed Martinez would be "part of the squad" for Sunday's Premier League trip to Leeds at Elland Road.
Asked whether Wilcox should explain his actions to the media, Carrick said: "I don't think it's for me to say whether he should or not. I've got no problem sitting here, talking to you guys and leading the group, leading the team, leading the football club from this position. We're all in it together."
Carrick said Martinez's statement was enough for the team to move on.
"He's released his statement, he's realised he's made a mistake, and I think that's enough for all of us to move on with," he said. "We ask for passion, we ask for emotion, we ask for fire and we ask for players to care. There's a way of doing that, and that's already been acknowledged."
United go to Leeds on the back of a five-match winless run, and Carrick said the club needed results rather than focusing on his own position.
"I don't need results. We all need results," he said. "It's not about me. Manchester United is a lot bigger than any individual. It is bigger than me, bigger than any player, or anyone else who works at this football club."
