The striker is now in talks with West Ham about a return this week.
Nolan told whufc.com: "Everyone loves Coley and I don't think there is a bad word to be said about him. I'm really pleased to see him and everyone has been pleased to hear his banter around the place and see his big cracking smile.
"We're hoping that can go over the line and he can be part of us again because he will be a great addition to the squad and he can produce what we need him to do.
"We'll see how fit he is over the next week or so but it's just great to have the big lad back and hopefully everything will get done in the next couple of days."
