According to the president of Milan, Silva and Ibrahimavic are being sold to PSG for 49 million euros!! If this is true then it's unfortunate because that's one less centerback that is a possible transfer. Even though Silva was a very unlikely transfer in the first place since he wanted to stay at San Siro, it eliminates more possibilities. He recently just signed an extension, and if he does move, it gives me hope that Hummels could make a move to Barcelona.
Another thing that apparently just came up is that Javi Martinez has announced that he will stay at Bilbao and reject offers from top clubs this summer, eliminating another possible CB transfer. Class CB's are slowly disappearing so the club has to quickly find an option, but not finding another bust. I still hope that a deal for Hummels works out somehow.
