I don't think KDB should be sold, but Foden needs to play his best position, cause he is our future and talisman.
RW - he can play, but playing him LW was a mistake, he is the player who can make the difference and against Arsenal his position was too limited to make that happen..
-------Rodri----Bernie/Kova-----
Foden--------------------Grealish
--------KDB----Haaland-----------
this can work, but the best position for Phil is this:
---------John------Rodri-----------
Bernie--------------------Grealish
--------KDB-----------Foden-------
-------------Haaland----------------
This is "Gundo" position. Here he can make impact, I think he has good connection with Grealish on the pitch and it will be beneficial for us. He can play and played KDB position well, but if KDB plays, then play him here and use his best skills...
When we had Cancelo, Cancelo was like LW and Foden was playing centrally
----Walker---John----Ruben------------
---------------Rodri-----------------------
-------Bernie--------Gundo-------------
------------------------Foden-------------
Mahrez------KDB/GJ----------Cancelo
For me it was something like this, but with Guardiol it isn't same and that's why he couldn't make any difference there..
Right now and this season's statistics also speak itself, Foden is our best-form attacker. So if we want results, we should utilise him and play where he is most productive.
And for the next seasons, if KDB stays and hopefully he does, Foden should play LCM AKA Gundo position..
---------John------Rodri-----------
Bernie--------------------Grealish
--------KDB-----------Foden-------
-------------Haaland----------------
This is our best attack..
