I could not see the point of bringing Buckley on in what was always going to be a battle in midfield, personally I would have brought on Nyambe at right back and pushed Bennet into midfield, but that might have involved playing too many players in there preferred positions.
Until we actually lose matches because of the injury, yes it is.
When Raya got injured at West Brom last season , that could have been a catastrophe, but it wasn’t because we took a point.
I think that post might have been said , tongue in cheek. with reference to TM's selection process. Personally I would rather play without a fullback than play Bell.
