I have Walker who is equally nailed, costs £2m less and I do not want double defense. It will also allow me to take KDB or Bernardo in midfield.
Walker is definitely not equally nailed as Cancelo. Last season's playing time between them both confirms this + age + Pep's talk of Cancelo being the most natural fit player in the squad (hence not so prone to rotation). However yes, he's a cheap route into their defence, if he plays week in week out. Too afraid to go with Walker myself though, I just see rotation coming into the picture with City's new signing.
