Paul Pogba could undergo foot surgery, keeping him out for 3-4 weeks.

Pogba missed Manchester United's 2-0 loss to Arsenal due to discomfort in his foot.

"We've had scans and it's nothing major, it's something that has to be sorted and dealt within a timeframe and he's been advised to do it as soon as possible, so he'll be out for three or four weeks," said Ole Gunnar Solskjaer.

With Scott McTominay also injured, Solskjaer added that United could reinforce the squad over the winter window.
