I mean, that's just not true. He literally creates chaos and his general play as a winger against the best teams in the leagues has been good. It's not, it's like if Hojlund is scoring nice goals for a period and being effective against the best teams in the league, we should work out how we continue to let him do that. Genuinely, so what if he's not the most effective 1 on 1 dribbler - Amad is miles better in that regard, yet that didn't mean anything recently.
His defensive qualities are on display for an attacker, not as a defender, not sure where you're getting the stats from but nothing is screaming top LB here:
https://datamb.football/P_Dorgu_Full-back_stats/. Compare him to an actual LB in Hall:
https://datamb.football/L_Hall_Full-back_stats/. You just have to watch how he played against Brighton in the cup as a LB, his general performances at wingback vs his performances as a winger for us and you can see where he's more effective. He's not though, you attack as LB very differently to when you play as a winger and you defend differently as a winger to a LB. He's not shown a good attacking instinct while having to cover a lot of ground (he'd have to do that whilst LB) and basic stuff like the first goal Arsenal scored against us for defending, he's average at. He has phenomenal work rate and physiciality, that doesn't make you a good defender, but it means you can defend well as an attacker.
That's fine as a premise, but it completely ignores the things he's good at and things he's not good at. I don't see why not if he keeps being effective, it brings balance to the team. I don't see how you could want to go into next season hoping he might be a good LB, despite watching him play well as a winger.
