One of the longest transfer sagas in football history was brought to an end on Friday afternoon as the Red Devils finally announced the Englishman's arrival from Borussia Dortmund.
The signing of Sancho could prove to be a game-changer for Ole Gunnar Solskjaer's side, as the winger is already one of the best players in the world.
In his four years at Dortmund, Sancho evolved from a raw youngster into a world-class operator and as a result, his value has increased rapidly.
According to Transfermarkt, he is now worth £90 million, which is far more than the £76.5 million United actually paid for him.
Sancho is the second-most valuable Premier League player and if he can hit the ground running in 2021/22, the skilful forward will take top spot in no time.
Let's find out who's ahead of Sancho by checking out the 30 most valuable footballers in the English top-flight on Transfermarkt.
