Hutton told BBC Sport: "Just look at Roy Keane's career in general. He's been there and done it. To have someone like that in your corner is unbelievable. He and Paul Lambert have worked unbelievably well together.
"Look at our performances, the ways we've gone about our games. It's clicked and there is no reason it can't continue. You want to perform for yourself but you know if you aren't [Keane]'s going to be there to give you the shot you need.
For me that's a good thing to spur you on, to get you back to where he thinks you should be. He's done brilliantly for everyone."
