Fulham sit ninth in the Premier League table ahead of their trip to Merseyside and have taken 10 points from their last five outings.
When the clubs met in January at Craven Cottage, it ended in a dramatic 2-2 draw as Cody Gakpo’s stoppage-time goal was equalised by Harrison Reed’s long-range strike.
On what makes Fulham an impressive team, Slot replied: “As almost always in football, the quality of the players compared to the manager they are having.
“They are having a manager that is already working a long time with them and you can also see that when you see them play. Clear structure, clear identity of how they want to play.
“Mainly with the same players I think in the last two seasons that I’m here now and maybe even for longer, but I can’t really remember how it was three years ago.
“We played last season at home, when we got the red card, it was probably one of the best games we played last season – which sounds weird but with 10 men we were really good. Twice we were a goal down and twice we came back. It was a 2-2 draw in the end.
“This season, I said it many times but that game maybe summed up our season, it was unbelievable that we didn’t win that one. If you look at the moment we scored, not that we played an unbelievably good game over there.
“But I think I saw it yesterday, but it was the 94th minute that we scored the goal. So, how often it happened then that you don’t win the game? Unless it’s Liverpool this season, then it happens a few times more.”
