Pique had an immense level in 14/15. He's a clown these days but here's his stats at his best:
ONLY 37 goals conceded in 60 games across LL (peak RM, AM, Sevilla), CL (PSG, City, Bayern, Juve), and CDR (peak AM).
His help was a declining Masche (great leader but he was getting on in age) and older Alves and Cryba lol.
He also played at extremely high level in 2018/19 except Anfield of course. I remember how he toyed with Real Madrid in 1-0 win in Laliga. Honestly, not many CB can toy with opponent like that.
