The "Special One" also stated that he has no pressure to keep all his players happy since only 11 players can start in a single match. Back-up goalkeeper Sergio Romero remains injured, but defenders Phil Jones and Daley Blind have both trained this week and are available.

Not for the first time this season at Old Trafford United started sluggishly and could have been a goal down after 12 minutes.
The Citizens had their fate in their own hands last weekend, but gave up a 2-0 lead at home to Manchester United, eventually losing 2-3, meaning they would have to wait for at least another eight days before being crowned champions.
The City manager's decision to forego the match looked justified considering West Brom's awful form, although Jake Livermore's early attempt was a warning shot that undercooked United failed to heed. United have kept a league-high 16 clean sheets this season with 11 of those coming in home fixtures. The Belgian scored in the return fixture against the Baggies in December a year ago and will be hoping to do more damage against his former side at Old Trafford on Sunday. All of their seven away league points have come against teams that began the day in the top half of the table.
The Baggies have scored just 26 Premier League goals in 2017-18, the same total Manchester United have registered in the first half in games alone.
