I don’t think Sancho agrees to go to the Saudi League. Plenty of players have rejected moving to the Saudi League, Lukaku is one such example.

From that Twitter post he made it sounds like he still rates himself. Fair enough, I’d really like to see how he does outside of United/EPL, people forget that Mbappe vs. Sancho was a genuine debate to be had at some point, talent like that doesn’t evaporate especially when a player has not had career ending injuries
