Missed the match and build up but was Aurier injured or just not selected? If he was fit it might have been wiser to start him at RB and have Tanganga in as a CB, he has the pace required but I suppose Mourinho may not be convinced by his concentration levels?A lot still being made of poor player performances and don't get me wrong, there's a tonne of those, and Sanchez obviously shown he can't handle the pace of PL now.
But, how much chopping and changing is there recently?
Different RB, different CB pairing, different combinations in midfield paired and then substitutions occur mid-game to then alter that too on non-figuratively a game by game basis? There's absolutely no consistency. If you have a different defence every game, it's hardly surprising we can't keep a clean sheet.
To your wider point it does feel like he's trying to find the right balance in defence but nothing is quite working for him. Whomever is selected just makes their own version of the same mistakes.
