The Reds saw a Dutch defender miss training on Thursday, while their skipper has struggled with illness, but both are available for a crunch clash
However, it later transpired Van Dijk was granted permission to return to his native Netherlands to receive royal recognition for his outstanding achievements this year.

“Last year [Kevin] De Bruyne couldn’t play against us, one of the best players in the world, and they still got results. That shows the quality of Man City. They are still really strong.
“Do I like talking about Man City all the time? No. I am more than happy with what we did in the last couple of years. But getting 100 points, then 98 points, and looking still greedy, that’s a really big strength.
“We all have to deal with setbacks and injuries, and they did pretty well.
“It’s not about comparing the team from last year, it’s about how do they deal with the situation and that’s quite impressive.

Klopp added as he prepares to be reunited with the side that pipped Liverpool to the Premier League title by a solitary point in 2018-19: “I don’t admire other teams, I respect them and I like a couple of things.
“The character of the team and the manager is pretty good, but the combination of speed and technique is always impressive in football.
“They have quite a few players who are good at that, organisation is pretty good. It’s a good football team.”
