Slot, who has previously won the Dutch title with Feyenoord, is in his first season as Liverpool manager after replacing Klopp last summer.
His side have a 12-point advantage over second-placed Arsenal.
There have been suggestions that the top flight has not been as competitive as in recent seasons but Slot believes it is a «difficult league» to win.
«I’ve only been here for a year so I can only tell you what I’ve experienced this season,» he said.
«I think it’s never been as exciting for top-four, top-five finish. In all the years before, it was quite clear which clubs will probably get the top three or four positions.
«In my opinion, it’s a really difficult league because that’s what I’ve experienced over here, there’s never been an easy game. It’s always been very hard to win a game of football.
«We are not the only team in this league who find it difficult to win a game by three or four goals. That was maybe easier two, three, four or five years ago.
«Either the teams are not so good any more — the Liverpools, the Manchester Citys and the Arsenals — or we are still very good but the other teams have the funds to spend just as much or, in some situations, even more.»
