It's just realism. I'd love him to disappear and us go and sign someone great to replace him but the reality is that we would be very likely to just sign someone who is at best as good as he is and so be absolutely no better off. There's an almost childish obsession from some people with him being the absolute worst player in the world when he's actually just a pretty standard PL squad player.
He was downright awful between 2021- up to start of this season so people are justifiable in those opinions.
This season when the team started picking up points he actually did o.k and Tarks looked worse. Than Branthy returns as ever whoever is alongside him looks good.
Don't really want to keep him though as to me it delays the urgent regeneration of the first 11. Surely J O'B showed on the final day he can have a good run at CB next season? He's done a good job at RB obviously but I'd prefer him to get more games ahead of Tarks next season centrally and then find a good RB to develop.
Then you release Keane and get in a younger CB to develop as J O'B eventually did this year.
Guess
Moyes is just thinking keep as much of the defensive unit around as possible but I think the issue there is when injuries hit and Keane has to start ten in a row.
He didn't do too badly last season but the issue is he makes those around him worse.
