I don't think anyone knows what Pep will do. He has shown a penchant for wierdness.
We know he incessant about ball retention. We know he is incessant about immediate recovery. And we know he is intense about keeping shape until the final Third.
He is more detail oriented than most coaches. In that sense he is a bit like Van Gaal. But more focused on ball possesion than defensive solidity.
As for who he'll favor vs who is doomed, that's justs speculation based generally on who specific fans don't like.
Every player has as good a chance as any other to succeed in Pep's team.
The notion that players like Yaya, Nasri or Fernando are out shows more of individual fans bias than any relationship to any discernible history Pep has shown.
