Parker, speaking exclusively to Goal.com via Betsson, the home of odds, said: "I have to say that they do need a new goalkeeper. If they’re going to move forward next season, they need players, fans and everyone to be confident in one of the most important players on the pitch; the goalkeeper. Top sides always have a top goalkeeper that they are assured with, and Onana is not that goalkeeper. I can’t see how he’s going to cover up what he did last season, and I just really don’t believe that he can. If I don’t believe as someone watching, I worry what the players in the team are thinking. If you don’t believe in your goalkeeper and you’ve got that fear factor, it will cost you."
