Man United's defeat to West Ham was indeed caused by the players failing to be clinical, and again they made a blunder (sloppy in possession) but even so, the one who should be blamed is their coach because he is the one who provides the strategy and chooses who becomes the starter, and Ten Hag fails to do so.
It's been long time about a months since that news start spreading around and I think that this was just agenda pushing by some group of people just because they are frustrated at him. No way Manchester United is going to say they are going to replaced him with Xavi, he is having an quality time there and wouldn't just jump back to Manchester United but I'm very certain That Erik Ten Hag is going to be sack by either end of the first leg or at the of the season, no doubt about that.
If they are going to bring a new coach, it will definitely be from outside Premier League, Laliga, Bundesliga. It is going to be the way they brought him from lord knows where and he had an amazing first season only to start playing low quality matches as if he wasn't the one that was getting all the credits all those times. At stage, the performance of Manchester united has gone from bad to worst, number 14th spot isn't place I think even Nottingham will dream of right now.
