By important contribution, I didn’t necessarily mean in terms of high game count or everpresentness. That is one way to get consistency in a back four, sure, but I don’t think it’s the only way. If Shaw had had a ‘normal’ season by recent standards, and Malacia had taken one step up instead of one step off a skyscraper or whatever, I think our full back position would have been the one in least need of recruitment. With how it is, it’s up to the medical team to say, but we have other positions I would focus on for the next three seasons if Shaw/Malacia could pick up where they left of.
Part of that is that I think we should at this point trust the squad enough to do more like Real Madrid, focus on one or max two top class and fairly young recruitments instead of an array of hopefuls and loanees. The decline of Varane, Martial, Eriksen, Rashford (?) and Casemiro may do this impossible this forthcoming window, but I think we should move in that direction and be patient.
