Arne Slot: Liverpool pre-season win over Manchester United not relevant at Old Trafford on Sunday
Liverpool manager Arne Slot is anticipating a different challenge when his side face Manchester United for the second time in a month.

Slot has taken charge of clashes between fierce rivals in the past, overseeing Feyenoord's meetings with Ajax during his time in Rotterdam, and he knows the importance of games against United ahead of his first trip to Old Trafford as Liverpool boss.

"One of the most important things is preparing (players) for what they can expect.
"What they can expect is mostly about the players they face, but I think now
