Celtic's Wilson: Forster is right behind Man City's Hart
The Scottish champions conceded an injury-time goal to Jordi Alba to lose 2-1 to the Catalan giants in the Champions League and it was goalkeeper Forster's performance which really impressed centre-half Wilson.
"That was a fabulous display from Fraser - he was absolutely superb throughout," he said of the former Newcastle United man.
"In my opinion, he is world class and right up there with the best. Joe Hart is the England No.1 but our guy is right there beside him as far as I am concerned."
