"I think he has been consistently the best goalkeeper in the Premier League this season," Pulis asserted.
"He's been different class for us. I think the experience he's got from playing games regularly has been the biggest factor.
"Asmir has had a full run at the team this season and grown in stature because of it.
"There is no substitute for playing games and that's why I would always encourage youngsters at this football club to go out and play league football to gain experience."
