Southampton defender Virgil van Dijk is good enough to fit in at Barcelona or Real Madrid, according to former Saints midfielder Jamie Redknapp.
The Netherlands centre-back, 25, has developed into one of the Premier League's most consistent and highly-rated defenders since joining from Celtic last September.
Redknapp, who enjoyed a spell at the South Coast side in 2005, told Sky Sports News: "Toby Alderweireld edges him as the best centre back in the league but he's not far behind.
"Van Dijk's the ideal modern day centre back and would fit in at Barcelona or Real Madrid - he's that good."
Southampton sit eighth in the Premier League table following Sunday's 3-1 win over Burnley.
