The Uruguayan came up against plenty in the way of top quality top-flight stoppers during his time with Liverpool.
But rather than name someone like Nemanja Vidic, John Terry or Vincent Kompany as the toughest defender he has ever faced, Suarez has instead plumped for one of his more recent foes in La Liga.
Speaking in an interview with AS, the 28-year-old identified Real Madrid stalwart Sergio Ramos as his most challenging opponent:
He said: “He’s the toughest defender that I’ve come up against. He’s very strong, competitive and has plenty of experience.”
Currently enjoying his spell in the limelight following Lionel Messi’s recent injury, Suarez has already scored 10 goals in 13 appearances for Barcelona this term.
That tally includes a memorable hat-trick against Eibar at the weekend, with the Uruguayan’s goals ensuring the Catalan club keep pace with Real Madrid at the top of La Liga.
