The Australian goalkeeper was criticised for his performance in last weekend's 3-0 home defeat to Tottenham but Jol feels he will be back in touch when the Cottagers host Newcastle United on Monday night.
"It is always the same," Jol said. "Three weeks ago we were all very happy at Fulham and two weeks later the situation totally changes.
"It is the same with goalkeepers. You make one mistake and everyone will doubt your quality and talk about it, but he is strong enough.
"He is a very good goalkeeper. He saved a lot of points for us so he will be back."
