I think everyone on here realises that he has limitations, when he’s not covered by a physical LCM his lack of pace and agility can be exploited as we’ve seen.
Hes another player we have that people tend to focus on the negatives of far to much again though imo, you mention his frame being a detriment to his longevity which is fair. But his height is actually also a big reason why he fits in so well when dropping into a back 3 when we go forward, it means we are generally defensively covered aerially down that side if needed in quick transitions.. and with Joelinton in front of him that left side is defensively solid all round. No balls over the top, no through balls.
I’d be surprised if he’s not our starting LB next season, obviously in an ideal un restricted FFP world the position could be seen as upgradable and no doubt he’d be replaced.
