I honestly can't believe there are still people who somehow think Sandro is better than Munir and is more likely to be kept by Lucho.
Munir is LUCHO'S BOY. The only B team player we have that we know with certainty that Lucho likes. Why would he loan him out?
Because there were some rumors about loaning him out. Anyway Munir, Adama and Halilovic can't stay in B-team next year - it's in their contracts. So they will either go to A team or they will be sent on loan. Sandro has no such clause, so he can stay in B-team and help A-team when necessary.
Munir situation will depend on Deulofeu - I don't think we'll keep both of them in A team. Also I believe team leadership wants him to have enough minutes, not sit on bench - and that's unlikely behind Trident. If they want him to develop his talent loan is necessity.
So ironically Sandro might have bigger chance to play for A-Team next year, precisely because he's rated not so highly as Munir.
