Gundogan says that he still hasn't decided about his future.
Roberto and rafinha will step up hopefully.
Roberto will step in surely.
Rafinha is already playing a lot.
What if Rakitic needs to rest or gets injured? Playing with Rafinha and Iniesta at the same time is a risk. Same with playing with Samper.
Also, about minutes, we don't need a player who will play 2000 minutes like Xavi, because we will 99% buy someone in January.
So, we need someone to fill only 800-1000 Minutes till January.
Iniesta, Rakitic, Rafinha, Roberto, Busi, Masch as a Dmf.
Samper will get some minutes in cup surely.
So, it is not that risky, even with injuries, as long as we get someone in January who will play in final Months of the Season.
Even now (without Xavi), we have 5-7 players for 3 positions.
