If Foden had been showing what Pep requires of him to play CM then I'm pretty sure he would have been the first one to put him straight into midfield and be just as eager as the rest of us to see him play there as he knows he's such a special player. The fact that he hasn't played in the middle for a long time now and especially in a charity match such as this just shows how far away he is from having the trust of Pep to play there.
Even in the last two seasons in the cup matches Pep would at least play Foden in CM even if he wouldn't be playing there in PL/CL matches but now even Palmer who could be considered Mahrez' replacement/successor at RW is getting a game at CM ahead of Foden who is naturally a CM.
I have watched him and he plays in one gear. Especially in the heat of the moment when the attacks are being constructed and the ball is with him and play is moving fast in the box, he doesn't slow his stride and give the "pause" amidst the chaos around him he just continues his movements in that one very intense tempo- again even Pep said this very phrase "His movements are all in one go". Personally, I have yet to see Phil produce what Pep requires of him.
Look at his younger contemporary Pedri, I love Foden but Pedri his poise and control and how he can shift gears effortlessly, he's already a master of Pausa at his young age, and why he's a fixture in midfield.
I hope this new contract doesn't make Phil get ahead of himself and focuses because as Pep said he can always improve and must strive to better himself every day.
