I think it's time to start giving Joe Hart a run in the team. Lloris was at fault for 2 of United's goals. He stood still on 1 of Newcastle's goals when it went right next to him, and he is costing Tottenham too many goals. Him and Sanchez have been the main cause of Spurs' poor clean sheet record.
Joe Hart is a leader in goal. He helps to organize the defense and in these crowdless games you can hear Joe Hart's voice booming across the pitch.
He is super-fit as shown in articles at the start of the season and was one of the best goalies in the PL and was England number 1 for many years. I would start picking him first choice and see how he goes before the Cup Final.
