Tottenham centre-back Cristian Romero has praised Virgil Van Dijk and Lisandro Martinez.
The Argentine international was asked about two of the best defenders in the Premier League at present.
He named the top two as Liverpool's Van Dijk and Manchester United's recent signing Martinez.
Asked by Sky Sports, he stated: "Today, the best defender for me is Virgil van Dijk - always - and Lisandro Martinez from Manchester United. For me, they are the best in the Premier League."
Van Dijk is a Premier League and Champions League winner, while Martinez has won multiple Eredivisie titles with Ajax.
The latter had a rough start to life at Manchester United, but has since won over fans and pundits with his tough-tackling displays.
