His words come after a stunning display between the sticks from Oblak during the victory over Liverpool in the Champions League quarter-finals.
''Chelsea are looking for a goalkeeper. He's been a top man for a long time.''
He was not the only one to hail Oblak's peformance.
Ex-Sunderland chairman Niall Quinn added: ''It was a tale of two goalkeepers.
''Oblak was absolutely superb, he was making saves all over and was impossible to breach at times.
''Liverpool will look back at this and say, 'How did these not go in?!', but you still felt even after that that it was going to come.
''It wasn't perfect defending by any stretch, it was down to their keeper who was really keeping it out.''
