Sol Campbell blamed Van Dijk for Liverpool's defeat against Aston Villa

Premier League champions Liverpool took a hard knock at Villa Park. Despite the fact that a week has passed, people still haven't forgotten what happened before the national team break started.

Criticism of Liverpool focused on Virgil van Dijk. "He had problems in the game, but he's being singled out these days because he's so far ahead of everyone else, which makes me wonder if this is hampering him at the same time," said former footballer Sol Campbell in 'The Athletic'.

"He's the most complete player in that centre-half position and he's made it look easy, but maybe he hasn't been challenged enough and then, like a cricketer being beaten by a slow ball, he's failing," said the Arsenal legend.

Campbell believes the Dutch centre-back is playing with "complacency". "If you haven't been worrying about the strikers bothering you, sometimes you drop your guard a little bit. It's a natural human thing, I think Klopp will bring it back," he added.

"It would have been interesting to see if Van Dijk would have stood out playing in our time, when there were many great centre-halves: me, John Terry, Tony Adams, Martin Keown, Jamie Carragher, Kolo Touré, Jaap Stam..." Campbell said.
