It will be Yaya, but it should be Navas. We have 4 players who can play his position. Nolito, Sane, Stering and KDB. We have 3 who can play Yaya's in Silva, KDB and Gundogan. 2 of whom are injury prone... I know many don't think of Gundogan as Injury prone. I do :P But either way, from a central ball possession standpoint we need Yaya as safety for Silva and Gundogan. I'd have gone with Nasri over all 3. But unfortunately :(Who should be left out of Champs League Squad ...Fernando, Navas or Yaya ....it will be Yaya me thinks but who should it be ?
