Longman is nowhere near as bad as many make out. Granted he’s probably not what you’d want to rely on as a first choice attacker if you’re wanting to get in the top 6 but he’s perfectly fine as a member of the squad.
I also think there’s potentially a lot more to come from him. He’s got good technique and can hit a wicked shot.
I actually think you could be right, he will always struggle here due to perception, a move away is still the best option imo.
