Elneny runs around a bit and people used to think he's good.
He had a couple of decent games when he first came but was pretty poor since then.
I believe Qwiss even posted his defensive stats and they were worse than even Cazorla's
When his passing is also so off it's blatantly negligent to leave him on.
Wenger is just a reactive relic and isn't going to win a league title here in his lifetime again.
