He's not good enough.
To be a centre-back at a top club, you need to be both dependable and a calming influence at the back. He's neither. He's 27 years old, and has now been here 5 seasons. In 190 league games during that time, he's only played in 65. And not since his first season has he played more than 13 league games. He's certainly not dependable.
Is he a calming influence? Not for me. Sure, he'll have games where he looks incredible. His speed and power will allow him games like that. But for me, he's too much of a loose cannon at the back, too wreckless. His tackle last night is a perfect example. Sure, he got away with it because of VAR. Regardless, why is he throwing himself into the player at such a speed in the box?
Why are people expecting him to turn around something in the next year or so that he has been unable to turn around in the last 4 seasons?
He's a liability if you look at his contribution to the team/club over the last few years.
So let's give him a new 5 year bumper contract.
