Bolton Wanderers captain Kevin Davies says they have one of the best goalkeepers in the world in Jussi Jaaskelainen.
"Jussi's one of the best keepers in the world," said the Wanderers captain. "Since I've been at the club he's been amazing and I can't think of a mistake he's actually made.
"He's one of the hardest working keepers I've ever worked with.
"He's always in early and will be in the gym before and after training. He works extremely hard and that's how he has become one of the best keepers in the world."
Davies also told the Bolton Evening News: "He can play until he's 40. When I first started, keepers used to carry a bit of weight and now they are extremely fit.
"It's up to him. I'm sure he will keep on playing but I'm sure he will go into coaching when he's finished.
"He works really hard with Ali Al Habsi and young Adam Bogdan, and they must find it great. He's really brought Ali Al Habsi on over the last couple of years."
