But Keane has faith that Ancelotti's meticulous work on the training ground can turn things around.
"The manager mainly does his work with us on the training pitch," Keane told the club's website.
"We have short team meetings before games so they [Ancelotti and staff] can let us know about our positions and how we will play.
"But most of our work is on the pitch. Our main focus is on what we do, we always know what to expect from our opponents but the important thing is how we want to play and our roles in that.
"I analyse every match with Davide, a couple of days after the game he will ask for a meeting following training – he does that with a lot of players.
"We'll go into the cinema room, all my clips will be up and he has notes.
"We run through my clips… I'll explain why I have done certain things and he'll say what could have been different.
"It really helps and makes you more aware of what the staff expect from you tactically."
