Liverpool open the Premier League tonight against Bournemouth at Anfield as defending champions.
Slot told talkSPORT: “Last season I also felt pressure on myself because everybody maybe didn't expect a lot. So that also comes down with a certain pressure. Everybody was saying after Jurgen, it's impossible, it's impossible.
“I think now we might need more time than we needed last season because the manager changed, but the players stayed the same.
“I've said many times that the playing style between Jurgen (Klopp) and me is not so different that it takes ages for them to be adapted to it. Now players need to adapt to each other and we also brought different profiles in.
“We cannot compare Florian Wirtz with any player we've got - maybe with Harvey Elliott - but he didn't play that much last season. And Jeremie Frimpong is a completely, completely different profile to Trent Alexander-Arnold.
“This is something that might need some time, but let's be clear, that's no excuse for our results in the beginning of the season.
“I think in the beginning of the season, everybody needs a bit of time. Because we're not the only team that brought in new players. The only difference is that we also sold starters.
“If I'm correct, our main competitors only brought players in and none of their players left. With us, it's a replacement. Very good replacements, by the way, but very good additions from the other teams as well.”
Slot also said of Liverpool's new additions: “They’ve come into a team that has a proper idea of how to play football, and that always helps you to settle in.
“I still have to adjust small things for the new ones coming in, compared with the ones that stayed, because they're not one-on-one the same players as the ones that left, and in my opinion it’s forgotten a little bit that three or four starters left the club as well.
“It's normal that people expect them to adapt so fast, because they are big signings, these players are good players. But still for them everybody will tell you that this is a different league than all the others in terms of intensity.
