Think the problem have had has been the midfield combination of Eriksen and Mainoo. What's becoming clear is that Mainoo isn't good defensively. So a midfield of Mainoo and Eriksen in a two man midfield struggles to put pressure on the ball.
On the ball, we're struggling to move the ball through the centre, as again, Mainoo isn't as strong positioning and acting on the ball in our defensive third. Add this to Eriksen not having the physical capabilities of making his presence felt, this then forces us to use our defenders to try and move the ball. In addition, playing deep at time due to the pressure we haven't applied in midfield, it means that our defenders are struggling to move the ball out of our half.
When we do get the ball up the pitch, we actually look good. Zirkzee and Amad are adding to our creativity, and Bruno can easily break any line.In the first few games, we relied heavily on turnovers from the press to create chances and have the ball in our half. This game is showing strengths and weaknesses. Ugarte might be a game changer both in and out of possession just on the basis of his physicality.
