Former Tottenham star Jamie Redknapp feels David De Gea is Manchester United's one big weakness.
He explained in the Daily Mail: "The biggest difference between the Manchester clubs is in goal where Joe Hart is a top goalkeeper and David de Gea appears out of his depth right now. Physically, he struggles with crosses and his lack of command was badly exposed for Blackburn's winner.
"Injury-hit United may have to make a change against Newcastle, when Demba Ba is likely to enjoy facing up to Michael Carrick. Time for Anders Lindegaard?"
