There’s nothing bizarre about it.
Sancho has been awful in the PL. But Sane was an absolute beast for us in the PL.
The only similarity between Sane and Sancho, they both have pace and play in the wide positions. But Sane is a better dribbler in 1 v 1 situations, akin to Grealish in a way and a far better footballer in the final third.
If you mean on a Judas level, Sane didn’t go to Utd or another PL team. He never came back to haunt us and he was very respectful to all the fans last season when we played Bayern.
I don’t think it will happen though, we have Grealish on the left, he was excellent last season. Would be fantastic to get another Grealish on the right though. Someone unpredictable who can run at a defence on the inside and cause pure panic.
