Aaron Wan-Bissaka 'has been ruled out of Manchester United's game against Arsenal with an unknown injury' in a fresh injury blow to boss Ole Gunnar Solskjaer.

United are already without first-choice left back Luke Shaw but the Manchester Evening News report that Solskjaer will have to do without £50million summer signing Wan-Bissaka on Monday night.

He was not pictured with the rest of the squad as they arrived at the Lowry Hotel but it remains unclear as to what has reportedly ruled him out.

Aaron Wan-Bissaka has reportedly been ruled out of Manchester United's visit by Arsenal

Wan-Bissaka has been one of the shining lights so far in what has been a difficult start to the season for the club.

If the former Crystal Palace full-back does miss the visit of Arsenal, United will likely turn to Ashley Young and Marcos Rojo as they seek a crucial win as they sit 11th in the table.

Sportsmail understands that Wan-Bissaka, who featured in the Carabao Cup penalty shootout win over Rochdale, has been managing a back complaint in recent weeks.

But while defence is becoming an area of concern due to injuries, Solskjaer has been handed a boost with Marcus Rashford and Paul Pogba pictured arriving at the hotel ahead of the late kick-off on Monday to boost the attack.
