Former Manchester City midfielder Nigel de Jong has praised his Dutch compatriot Virgil van Dijk for his impact on Liverpool's team during his first year at the club.
The current Al Ahli midfielder has also claimed he is surprised by how much the defender has improved since moving to Anfield in January last year for £75m.
Van Dijk made his 50th appearance for the Reds during Saturday's victory away at Brighton in the Premier League. The 1-0 victory also saw Liverpool complete their 23rd clean sheet in the 50 games of which the Dutchman has featured in their side.
