Manchester United manager Ole Gunnar Solskjaer has defended Cristiano Ronaldo
Ronaldo has struggled for United in the past two games.
But Solskjaer said: "There are 11 players with different roles and responsibilities. We put a team out we think will win. We didn't beat Leicester so there is always criticism when you don't win.
"Cristiano is a top player and we know what he can do. He is doing everything he can to help the team.
"Of course it is not a gimmicky, jovial and happy camp. We are focussed and determined. You look at yourself and ask what you can do to help the team.
"I have seen a reaction. Conceding four goals [against Leicester] is a big eye-opener and we need to improve on different levels and on loads of detail.
"Winning at home against Atalanta would be massive and a big boost."
