Former Arsenal defender Martin Keown believes Liverpool duo Virgil van Dijk and Joe Gomez could become the Premier League's best centre-back duo.

With Joel Matip and Dejan Lovren on the sidelines, Gomez started alongside van Dijk in last weekend's win over West Ham. And Keown, who played over 300 times for the Gunners, was impressed.

He told the Daily Mail: "I was seriously impressed by the partnership of Joe Gomez and Virgil van Dijk in the centre of Liverpool's defence.

"There will be few better partnerships in the Premier League this season.

"I have been arguing for some time that Gomez should be playing in that position and against West Ham, he showed why.

"Marko Arnautovic is the sort of player who will cause defenders problems if you don't get on top of him quickly. Liverpool's centre backs swatted him like a fly.

"There will be bigger tests to come this season but Gomez and Van Dijk purred around the pitch like a pair of Rolls-Royces.

"On Sunday's evidence, Dejan Lovren will find it tough to win back his place. These two have the makings of a great Premier League partnership."
