Agree to some extend but need context. We have solid full back defending and helping with attack back then. Also not to forget SAF's tactic place heavy emphathy on wing way. Also the conductive SS, third midfielder with ability to play wide help, be it Giggs, Fletcher, Anderson, Rooney, even Cleverley... This means when the wingers, wide attackers swap wing, we maintain the solidity of the team structure. This teams, our no 10 ain't that good in their primary position, let alone stay wide for too long in transition phase. Problem with left back position is huge. The potential ain't fulfulifn theirs. The disciplined defensive sound can't attack. The more balanced is lukeswarm and need stability in system to help them out... thus making it a big miss to constantly swap wide players in game. Rashford is more blanked option on the left which understandably preferred in many of partnership on the left side with our left back.
