Warnock said: "They were two great saves by Paddy Kenny, but that's what he's all about. There isn't a goalkeeper in the Premier League who's better than him. I wouldn't swap him for any keeper in the country.

"I've told Arsene Wenger about him many times down the years, but he hasn't been interested and I'm glad about that because I wouldn't want anyone else."
