Barcelona's monetary problems are well known, so much so that La Liga president Javier Tebas commented on the matter earlier this year.
“They have two or three top-class players they can sell. If they sell them, then they can solve a great part of their program. With that, they can generate income that doesn’t generate debt interest and can pay players," he said.
That may mean players like Kounde could be sold, and potentially for a fee below what they would like - opening the door for sides such as Arsenal.
