The thing that must be difficult for Poch is that when Dembele turns it on he is unplayable. Against Fulham he turned the game completely in our favour. I can see why Poch persists with him even though he is not the player he was 2 seasons ago. We simply do not have a suitable replacement.
I genuinely cannot remember the last time Dier had a good game. I was a fan, I really was but defensively he has been a liability for some time. He fails to dominate when defending set pieces, I have lost count of the times he's bullied off the ball or fails to get distance on a headed clearance; he commits Walker style defensive errors with alarming frequency (got away with it yesterday but didn't the last time we played Liverpool) and for a big guy he gets turned far too easily in midfield then gives away a foul to make up for his error.
Not sure if I can accept that these things are solely down to the number of games he has played. I would be interested to see a comparison of the number of games he has played compared to Eriksen, Kane and Ali. He seemed to spend most of the world Cup collecting splinters on his arse from the bench.
I don't trust him to play centre half and he cannot hold in midfield on his own. Not sure where we play him perhaps as a right back? He just hasn't pushed on and with Dembele not performing as well as in previous seasons Dier's weaknesses are being exposed more and more. Sad as I am to say this we need to upgrade on him and probably Dembele and Wanyama too, although Dembele even with the way he has played the last 2 games will still be very difficult to replace.
