After going a goal down, the Reds fought back through strikes from Hugo Ekitike, Virgil van Dijk, Ibrahima Konate, Cody Gakpo and Dominik Szboloszlai.
Slot said afterwards: "Maybe yes, although I saw a lot of similarities in the last few weeks, in the last few games we played. I also saw some differences. The similarities were that we already create a few chances before we conceded the first one and the first chance we conceded was usually a goal. In the end it turned out to be the only chance we conceded today.
"Why was that? Because we went 3-1 up and so then it's easier to control the game than when you're 1-0 down all the time. I've said here a few times telling you guys how important set-pieces are, how important the balance at set-pieces is. Now we were able to score two so you go 3-1 up at half-time because you score two set-pieces.
"That is a big, big, big difference and you go in at half-time at 1-1 with still the same amount of chances, but people will judge us definitely differently when you don't score them.
"The biggest exception for me today compared to the other games we've played was the playing style of our opponent. We got some energy out of the moments we could press them, which in the last four or five games we played we were not able to press the opponent because the ball wasn't on the ground, it was in the air."
On Ekitike, he also stated: "The first goal we scored was special. You could see his pace in a moment like that. These were also moments we were also hoping for. Like I said before the game, we were able in the last few weeks to create many, many, many chances but unfortunately we were not always able to score them."
