No.
(1) We should forget about him and mostly play Dalot in a formation using wingbacks. Wan-Bissaka is not attacking enough for United. We always play converted wingers as full-backs anyway. Look how many games Darmian got - hardly any. Same will happen to a defensive fullback like Wan-Bissaka.
(2) The money's needed to improve other areas first. Apart from the #11 = James, we need a #7, CB, DCM, #8, and, possibly a #9 if Lukaku leaves. It looks like Ole is happy with Lukaku leaving. That's between 5 and 6 in during summer. There's also talk of a goalie to replace de Gea!
(3) We already have: Dalot, Young, and Darmian for right-sided fullback.
(4) New #2 is the lowest priority.
