#1 He’s a better defender
This may come down to personal preference, but the proof is in the pudding for this one. At Barcelona, defenders are afforded ample amounts of possession meaning they only have to defend on the rarest of occasions.
While at the Bernabéu, Los Blancos play in a counter-attacking system that relies more on 1v1 defending. This means Ramos is often tested every game regardless of the quality of opposition.
Over the past five La Liga campaigns, Sergio Ramos has made 1.6 tackles per 90 minutes, compared to Piqué’s minuscule 1.44. The Madrid captain has also made more interceptions (2.53) than Gerard Piqué (1.95) per 90.
This shows the 31-year old not only has more defending to do, but when he does do it, he’s superior to his Spanish compatriot.
