The Champions League is back, and there aren't many harder tests that Liverpool could have been handed for its opening league phase game.
The Reds host Atletico Madrid at Anfield later, with Arne Slot's side aiming to make the perfect start as they begin their European adventure as one of the favorites for the competition - although Diego Simeone is unlikely to make things easy.

The deadline day signing is expected to make his debut against Atletico, and Liverpool's boss has hinted that he could even start at Anfield.
