Liverpool's form has been poor this season, with underperformance from individual players being a large reason as to why. Looking at their playing personnel, it's difficult not to think that their exploits over the last few seasons have taken their toll in both a physical and mental sense.
The makeup of the current squad certainly doesn't help. While there have been a few additions over the last few seasons, it is largely the same core group that has been together since the 2018/19 season. As a result, it is an ageing group that looks unlikely to rediscover the magic that has gotten them to this point.
Virgil van Dijk is one player who has come in for some heavy criticism in recent times, with some believing he has lost the aura he possessed when he was widely considered to be the best centre back in world football.
Ruud Gullit launches attack on Virgil van Dijk
It appears even those in his home country are now starting to ask questions about Virgil van Dijk, with Ruud Gullit making some very harsh comments after his recent form.
Speaking to Ziggo Sport, the Dutch legend questioned the defender's approach and said he needs to show far more leadership among this group of Liverpool players.
Van Dijk puts his hands behind his back like a speed-skater and he bends his knees like speed-skaters do.
His body is leaning forward. He kind of kneels down in his moves and only has his hands behind his back so he avoids a handball when the striker shoots.
That, for me, is too easy - and it looks clumsy...
When Van Dijk came back after his injury he was defending without aggression. It was passive.
He stands there like a skater, defending and blocking a bit. He just does not go full on.
Of course, every player can have a bit of a less brilliant period. But Van Dijk has to be the leader. If the defence is not going well then that is his responsibility...
Everyone looks up to him. He has a massive status. But right now is the time that he shows leadership to those around him and in that Liverpool squad.
It is chaos in the Liverpool team. I almost feel sorry for Jurgen Klopp.
The whole squad is one drama and I think it was a mistake to let Sadio Mane go. But that is Liverpool’s own fault...
Van Dijk is a great player, one of the best defenders in the world. With Joe Gomez next to him, he does not have the greatest of partners right now.
But when you concede goals like they did against Real Madrid it is time to get your act together.
Fairly damning.
A return to form from Virgil van Dijk would go a long way towards arresting Liverpool's recent slide, although it remains to be seen if that can be achieved in time to salvage the current campaign.
