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.
