Keane worked with Rice in the Republic of Ireland national team set-up.
"Where he needs to improve… there's plenty of aspects…" Keane responded. "When you think about him over the past few months he's had a lot of praise."
"I've looked at him pretty closely, worked with him when he was with the Irish squad, but where he needs to improve… where do you want me to start?
"His positional play. I don't think he's been consistent enough. He doesn't stay with runners. He's sloppy in possession… I can go on.
"He's one of these who I think a couple of months ago everyone was enjoying him and loved him but I think he's one of these players who's almost played his way out of this team because he's not been consistent at West Ham."
