Cardiff City fullback Kevin McNaughton can see goalkeeper David Marshall moving to a bigger club.
The Scot has been linked with Tottenham in recent weeks.
"I think he'll go on to better things and he'll probably for a top-four, five team in the division.
"We're just buzzing that we've got him here and he's signed an extension and it's great for the club he's playing for Cardiff," fellow Scot McNaughton told BBC Radio Wales Sport.
"He's probably just beginning to hit his peak now. He's done a great job and I think he's probably one of the best in the league if not the best.
"I can't really see anybody else who's produced the sort of saves he does week in, week out.
"I know he's getting tested because we're allowing him to be tested but every time he's asked to make a save he's been brilliant.
"But I think he's been doing it over the last two or three years and stepping up to the Premier League is a lot more difficult and he's been class, he's just dealt with everything.
"I hope he stays at Cardiff for a long time. The way he's playing at the moment it looks like somebody will probably come and try and nick him off us."
