Gattuso concedes his players are struggling for form.
He said, “In times of emergency this is a team that surprised everyone, who played with enthusiasm and the sense there was nothing to lose.
“I remain very disappointed by the first half my team played, Frosinone looked like the team playing for fourth place.
“Three days ago we were one point from our Scudetto, which is the Champions League.
“We're a team that wants to do things, but always does them halfway. We've fixed the defence, now the attack is the problem. Every time we shoot there's the sensation we're not going to hurt our opponents.
“It's already difficult to wear the Milan shirt, we need to make our mistakes without getting depressed.
“Mistakes happen, the important thing is to remedy them and make yourself available again. Lately the opponents win every 50-50, I think it's a mental issue.
“I think fear has taken over."
