It’s obvious it’s big Gabi. Kos was good, but we were a banter team in those years. He was also easily bullied by bigger attackers, not that great in the air, and average distribution. I get rose tinted glasses but does anyone think Kos would be in the starting 11 of the curent team ?
For me the pairing has be Gabi and Saliba. If someone offered me peak Kos or peak Mert to replace Gabi, I wouldn’t take either. Mert was far too slow for the football we play, and Kos was good but not great. It’s clear for me, Gabi and Saliba all the way
Xhaka first 3 years could easily be in there
