They have reduced their wage bill in the summer by selling or releasing big earners like Suarez, Rakitic, Vidal, Turan and Rafinha. They also made a profit by selling players like Semedo and Arthur. Their squad is quite small now. I don't know if they will let lots and lots of players leave but if that is where Richarlison decides to go, there may be a chance to look at players on the fringes like Emerson, Umtiti, Fernandes or maybe Riqui Puig (although I could see Barcelona wanting to include a buy-back clause with him)
