If he'll play like he is playing in 2016 and if we won't win La Liga or a CL, some players will get sold.
Older players, foreigners, and older foreigners are the first one in a row (Arda, Mathieu, Rakitic, Mascherano), plus huge flops like Vidal, Paco or players who didn't play at all like Cillessen.
So, if results won't be good at the end of the season, there will be changes.
If we would be too emotional, then we couldn't ever sell neither Rakitic, Mascherano or any player who was a valuable player in the past.
That way we could sell only flops like Arda, Vidal or Paco.
But again, there will be way more changes and sales if we won't win trophies.
About Rakitic, we have a somewhat similar younger player in Gomes.
Plus, we will promote Alena soon, plus we will buy at least 1 new expensive Cm in a summer 2017 or 2018 (something like Coutinho/Verratti).
So: Gomes, Denis, Iniesta, Alena, Coutinho, Rafinha (Arda, Rakitic), Roberto (as a Cm?).
Some players will have to go.
