This fixture is a valuable test for Erik ten Hag’s side, who finished our tour of Australia and Thailand unbeaten, and seconds away from recording a 100 per cent record.
The Spanish giants will be awkward and much-respected opponents but the Reds must want to set things straight by defeating the side who narrowly eliminated us from last season’s Champions League.
WHERE'S THE MATCH BEING PLAYED?
United will take on Atletico in the Ullevaal Stadion, the home ground of the Norway national team.
Kick-off at the 28,000-capacity arena is set for 12:45 BST.
