Has been good in this recent run but after Sunderland scored, the game dynamic changed. We're chasing goals against a deep and dual layered defensive block. Lingard is good at building play and keeping it safe but he's not the best option we have at forcing a position through runs beyond the defensive line, stretching play, shooting or dribbling past a man. He can do them all but simply put, Memphis offers more than he does in those aspects.
For that reason, I'd sub him at HT for Memphis. Though that does leave Love in a very insecure position defensively. Would need the Carrick-Schneiderlin double pivot to really work hard and close the spaces necessary to cover as much as possible.
Might be better to have Rooney from the right, Martial probing centrally and Memphis wide left considering our attacks have been predominantly down the left anyway.
