But he hasn't been used that way by Pep when Cancelo is on the other wing.
He got 1 assist last season across PL & CL.
I have seen him going forward plenty under Pep at City. He certainly has that threat that teams have to respect even if he is doing it a lot less than he has in the past or Cancelo does, with a guy like Tomiyasu there is nothing to respect because him going forward is great for the opposition.
Also, assists tell very little about what players contribute offensively.
Edit:
I would also say if we had a MF with the creative options that City did and a manager like Pep that can create offense not a dinosaur dud like Nuno perhaps I would be more open to the idea of having one FB that is useless in attack.
