Manchester United boss Ole Gunnar Solskjaer has responded to comments from former team-mate Roy Keane.
Keane criticised United after they were beaten by Arsenal in the Premier League at Old Trafford.
Keane, working as a pundit on Sky Sports, had said: "It’s not that I don’t see enough of them, it’s that I don’t see any leaders out there, right through the whole team from the experienced players."
Solskjaer is under pressure again as United boss and admitted his side found life tough against Mikel Arteta’s side.
"Well, in the first-half there were no tackles, no fighting, you have got to create an atmosphere yourself," Solskjaer said in response to a question about Keane's comments on Sky.
”These games against Arsenal were always fierce, tackles flying. We didn't have the tempo or intensity for that, absolutely, and I was disappointed with the first-half performance.
"In the second-half we were better, unfortunately they got the penalty and we just couldn't produce the response.
"We prepared well, we prepared [the players] for a big game. Arsenal is always a big game, sometimes it's hard to pick up where you left off because that's not how it works in football.
"Everyone wanted to do well, of course, we just couldn't get going. That's why we have a big squad, a good squad and today we couldn't produce the performances that we've seen before.
“That's football for you. We play against very good players as well."
