Rio Ferdinand has questioned what Wout Weghorst brings to the No.10 role after West Ham's 1-0 win against Manchester United - with other players waiting in the wings.
Erik ten Hag's side were beaten at the London Stadium on Sunday after David de Gea failed to keep out Said Benrahma's weak long-range strike. The result leaves Man Utd fourth in the Premier League, just a point ahead of Liverpool in fifth with a game in hand.
Ten Hag likes to play Weghorst in the No.10 role, with Bruno Fernandes moving out to the right flank and Marcus Rashford playing at centre-forward. The tactic has been criticised and Ferdinand is struggling to see how it benefits Man Utd's attacking prospects.
