Barcelona coach Pep Guardiola can understand Adriano wanting a move.
The Brazilian left back is considering his options this month.
"If Adriano leaves, then maybe we'll have to return to the market," said Guardiola. "Any player here is free to leave if he wants. The ones left are the ones who want to stay. From Messi, to the youngest junior.
"I do not want anyone to be unhappy or feel forced to stay."
