Agree with that in parts.
But if he is as bad as some make out, he'd already be replaced by at least one of Winks, White, Skipp, Lo Celso.
Obviously some of those are youngsters just at the start of their careers, others might not be up to the job and maybe one or two of them aren't good enough.
Maybe (hopefully) Skipp will replace him next season, but it does show that of all the midfielders we have (or have had at the club) that he is regarded as being better than them. By two separate managers with different footballing philosophies.

said, if you're looking at our "best eleven" he'd definitely be the one of the first on the list to be upgraded, but that doesn't mean he hasn't done a job for us.
