I would like to see us having more control in games. Right now we are simply incapable of keeping the ball for a sustained period of time. Ralf has clearly highlighted this early on as a problem but so far has failed to address it and let me tell you, playing 2 midfielders in the PL, especially those midfielders being Fred and Mctom will not solve that!
I think the Palace game, especially that 1st half, has somewhat clouded his judgement. Ever since then we've looked disjointed and a complete and utter mess. I kept saying it when Ole was in charge but we need to have 3 midfielders if we are to have any sort of control of possession, so a 4-3-3 formation is the way to go. The problem with that is what do you then do with Bruno, who arguably has been our most productive and important player the last 2 years. Then you have the question about Ronaldo, who whilst has been great in the CL, is actually quite poor in the PL and is very rarely involved off the ball, we need someone like Cavani. For the game against Burnley, I would like to see the following lineup:
---------------------------de gea------------------------
Dalot----------Varane------Maguire------Shaw
-----------------VDB-----Matic---Fred-----------
Sancho-------------Cavani--------------Rashford
If we want to add even more steel to the midfield, swap VDB for Mctominay. Once bruno is back, we could even switch to this formation and rely on width from the fullbacks:
---------------------------de gea------------------------
Dalot----------Varane------Maguire------Shaw
-----------------VDB-----Matic---Fred-----------
-------------Sancho----------------Bruno--------
-------------------------Cavani--------------------
Tl;dr: Stop playing with 2 strikers, swap one of them for a midfielder.
