Liverpool’s defence has been really impressive this season.The backline has been a problem for the Merseyside club for a considerable number of years. In the 2013-14 season, in which they so nearly ended their wait to win the Premier League title, they conceded 50 goals.But Jurgen Klopp has built a quality group, spending huge sums to add quality in Virgil Van Dijk and Alisson Becker and getting the best out of Trent Alexander-Arnold, Joe Gomez and Andy Robertson.The Reds have conceded just five goals in 12 leagues matches; no team has allowed fewer.Indeed, Alisson recently said he’s had to switch up his own play style because the defence is so good.“My team have a really great defence so it is not often the ball comes near my net,” he said, per the Liverpool Echo.But all teams are striving to improve and Van Dijk is in regular contact with one of the most promising defenders in the world, Ajax’s 19-year-old centre Matthijs de Ligt, due to their partnership for the Netherlands.

Van Dijk discusses De Ligt

That would put Liverpool in a good position in any attempt to sign the young defender, who has reportedly attracted interest from Manchester City and Barcelona.

Van Dijk is a huge fan of De Ligt’s, raving about him to Dutch newspaper De Telegraaf.

And the Liverpool star added that Anfield scouts will already be scouting De Ligt.

"He is already very far, especially at that age,” Van Dijk said. 

“A good defender, good boy, calm, knows what he wants and hopefully he makes the right choice in his next step."

A partnership of Van Dijk and De Ligt at Anfield would be very exciting. But Van Dijk insists he doesn’t need to alert Liverpool to the teenager’s abilities.

"He will be on the list, because they have enough scouts at the club,” he added.

Van Dijk was then asked if the best scout would be him, considering their international partnership.

“No, but if they need my opinion at Liverpool, I'll give it,” Van Dijk replied.

There are suggestions that De Ligt will one day become the world’s most expensive defender, surpassing the record £75 million that Liverpool paid Southampton for Van Dijk.

The Liverpool defender said he will congratulate De Ligt if that happens - although he doubts any club will pay as much for the youngster at this stage in his career.

“No, they will pay less for Matthijs. The amount for me was very high, though," he added. 

"No, in all seriousness. It's just like that and, if he ever becomes the most expensive defender, I'll be the first to congratulate him."

Van Dijk's words have left Liverpool fans very, very excited.
