Manchester United boss Ole Gunnar Solskjaer is under no illusions about the threat of Atalanta.

United host Atalanta in the Champions League tomorrow night.

Solskjaer said: "I'm very impressed by the Atalanta way. The style the play with, the way they develop players, their results, and then their manager, who is clearly very strong and he wants his team to play in a certain way.

"We signed Amad [Diallo] from Atalanta and we have watched them quite a lot. It is a team with an attacking philosophy, which most football lovers like. They will cause you problems with good individual players.

"Amad trained with the team before the Leicester game and he is continuing his rehab. He will probably play for the U23s soon, when he is ready. His development has been exactly what we want, he is learning the language well and how we play. He is strong on the ball but the injury was bad timing. We will have to make a decision before Christmas whether he will stay here and play, which is a possibility, or if he will go elsewhere and then come back in the summer."

Marcus Rashford added: "They [Atalanta] have an aggressive type of play, both in attack and defence. It is definitely going to a tough and intense game but it's the type of test that we want. I believe this game can bring the best out of our players, so hopefully we get the tough game we want and can show people what we can do."
