Yes, but the problem is who is covering that 6 space when Bents is in the 8 space. That is the problem I see in Ange's system. I don't see the other 2 midfielders spending any significant time there. I'm not even sure that is the plan anyway. I wonder whether it is the full-backs job to tuck in and become the defensive 6. Pep does it the other way, where he lets Walker become the centre half and Akanji become the 6.
What is interesting is that Conte was all about zones. He had Bents as a superb number 6 protecting our back four. When he first joined, Bents would position himself well, he would eat up the ground and cover all the gaps. He was also good on the ball. Now we're saying he's not equipped with the right skillsets. Is that really true?
Ange's system (in it's basic form) is 4-3-3 out of possession transitioning to 2-3-5, The FB's do tuck in alongside the 6, then the two 8's need to know if the 6 or the two FBs (who definitively do) move forward into space, they need to swap back (we have seen Maddison and Udogie swap multiple times in an attack)
Bentancur was on the verge of being elite pre-injury, he carried that Conte midfield (Conte's system issue was he pretty much guaranteed the midfield would be outnumbered in most games, so from a possession perspective we would struggle to consistently out possess the opposition and dominate them via midfield, not an issue with Ange, we out-possess everyone). Is Bentancur that player now? don't know, this season will tell but the argument remains that a purely DM minded midfielder could help.
I still think it's a balance issue, who's the right mix between Biss, Bentancur, Sarr, Gray, Bergvall, Maddison and how do you squeeze Kulu into that midfield?
