I`v got a corker 18yr old 4 star MC with play maker for 1 token and 8 skill of 5 star here`s my dilemma my squad is all 5 star and can be 6 star, so do i train the hell out of him meaning buying greens to get at least 100 skill points on him to get near quality of other, if i do this it means i can sell my 22 yr old MC/RM ?

OR do i train to 1 skill (need 7) from 5 star and let the bidding war take over

said player is 89 but if i add skill to other they will be 97 rated
