Manchester United could be without captain Harry Maguire for the clash on Tyneside this Saturday night.
Maguire's nightmare week - after being sent off for England in the awful 1-0 loss to Denmark at Wembley - could be capped by his absence in the crunch game at St James' Park.
The Red Devils are already without Edinson Cavani (quarantine) while Facundo Pellistri and Alex Telles could also be sidelined.
Anthony Martial is also banned from the encounter after a red card against Spurs in the 6-1 defeat at Old Trafford before the international break.
Ole Gunnar Solskjaer said: “Harry seemed to pick up a little knock just before he got sent off.
“So we’re having a look at him today to see how he is
"Alex has travelled all around the world.
"He flew overnight and got here on Thursday."
