I'm pretty sure that one of the reasons Pep will go for him is that he showed that he can play as an 8 (at times) for the national side during the Euros last summer as well, cos I dont personally think he will get enough games as a pure 6 for Rodri. I dont think Pep likes rotation on that one (position) too much, not as much as the rest of the team at least.
His injury issues this season is a worry though, seems like he played every game for a couple of seasons and the summer as well.. maybe it finally caught up with him and he won't have as much issues if hes handled with in the future.. Bielsa (training) is a madman as we know.
And in some ways its easier now as well.. cos there's no way hes gonna leave, for instance to Villa when Leeds is staying up, which he might have felt "forced" to do if Leeds went down with the 25m relegation clause, and would have gotten more playing time at Villa than Man City as well. That equation is kinda taken off the board now. Now its more of a pure choice with staying at Leeds or leaving to City for a somewhat more restricted role.
