Yeah I agree. it is a funny worry people have when they say we don't have CBs for a back 3 and we need to buy CBs or WBs who know how to play a back 3, as if there are CBs and WBs out there who have been training since the youth teams to play those positions. All the defenders who play in a back 3 have come up playing in a back 4 and have been coached to play in a back 3 at some point in their career. Same with the wingbacks. All our CBs with some coaching can play in one position or the other in a back 3. At WB just due to more demands for stamina and 1 on 1 attacking I can see the argument more but even then, both Mazraoui and Dalot are perfectly capable to play those positions, as are Shaw and Malacia if we ever see them. Even the wide CB positions shouldn't be an issue as the majority of CBs nowadays defend 1 on 1 in the channels anyway. Its not as big an issue as some people make out.
