Erik ten Hag used Luke Shaw at centre-back again in the FA Cup on Friday night, a move that is far more than just an emergency measure and which inches both Harry Maguire and Victor Lindelof that little bit closer to the Old Trafford exit door.
The Manchester United boss elected to start the England left-back alongside Raphael Varane at the heart of the Red Devils' defence in the third round victory over Everton. That was despite Lisandro Martinez, Lindelof and Maguire all being available, with all having to make do with spots on the substitutes' bench.
In explaining his decision, the Dutchman insisted using Shaw in the position in which he is becoming increasingly familiar in recent weeks, was a "tactical choice", having been extremely impressed with how Shaw has taken to the role since the World Cup.
