Van Dijk’s arrival from Southampton has undoubtedly made Liverpool look more secure at the back, but has Coutinho’s exit played a part too?
“When Coutinho was playing in a deeper midfield position, you are almost losing a man defensively,” said Warnock.
“Yes, he closed down – but he does not close down like the current midfield trio do. That is a big reason Liverpool have been doing so well.
“It starts from the front, of course. I was at Etihad Stadium to watch Liverpool beat Manchester City in the Champions League and at times only their three forwards were pressing six City players around their area.
“The Liverpool trio of Mane, Firmino and Salah were outnumbered but they were very clever with the way they did it – with their body shape as they closed City players down and their speed and acceleration.
“They actually decelerated at the right time too, and it was brilliant to watch. It must be a nightmare for defenders, who have got those three running at them one way but also hassling them when they are on the ball.
“Liverpool’s forwards are just as quick to close you down as they are when they are attacking, which is frightening really.
“Behind them, they know they have got three more players doing exactly the same if the ball does get through.”
