Derby County defender Curtis Davies thought that his club signing Wayne Rooney was a joke at first.
The Championship side managed to lure Rooney away from DC United in the MLS in January.
Davies told talkSPORT: "It's been a bit of a rollercoaster season, to be honest.
"Wayne signing was massive. When we first saw it on the news we thought it was a wind up.
"Him signing was massive. He's obviously come here for different reasons. He wants to start his coaching career with the club as well.
"That's helped us to get him in but the job he's done on the pitch has been fantastic and he's been what you expect from Wayne Rooney.
"He's been top quality and he's been using it both for himself and also for the young lads to help them come through too."
