Arne Slot doesn't seem to have struggled with anything since taking charge at Liverpool. But the head coach has revealed one thing he has found hard.

On the pitch, there has hardly been a hiccup. Slot takes his side to face PSV tonight, knowing that a win would make it eight wins out of eight in the Champions League — but he will rest key players, because he's fighting to maintain a healthy lead at the top of the Premier League too.

Succeeding Jurgen Klopp was not meant to be this, well, easy. Of course, credit must go to Liverpool's previous boss for leaving behind such sturdy foundations, but the season that is unfolding is beyond even the wildest expectations.

Talk of a quadruple seems to emerge earlier and earlier these days — Joe Cole was the first to break the taboo recently. That's clearly hasty, especially as Liverpool has left itself with work to do against Tottenham in the Carabao Cup, but it underscores just how impressive the Reds have been in Slot's debut campaign.

Yet it just goes to show that even when everything is coming together, being the man in charge of Liverpool Football Club is a tough job. In conversation with Gary Lineker, Slot has admitted that it puts a strain on his family life.

Slot's family is back in the Netherlands. He opened up on the sacrifice that entails:

"That is hard," he admitted to Lineker. "The good thing is that it's only an hour flight.

"The children go to school and are in their exams. But they've been here quite a lot, especially in the first half of the season when we've had a lot of international breaks.

"The most difficult period is for me now. After November until March, there is no break in England so that means it's a bit harder as you don't see them as much as you want to.

"This gives me a lot of time to prepare and do my work so maybe I'm a better coach now than when I was in Holland."

Selfishly, Slot becoming an even better coach between now and March would be a welcome development. It's not clear how much room for improvement there really is, but flawless form between now and then could all but wrap up the title for Liverpool.

But it's always valuable to be reminded of the human realities of top level football. Slot is very well-remunerated for what he does, but there's no denying that it involves a level of sacrifice — let's hope he is rewarded with some silverware come the end of the campaign.
