If Thiago Silva is really going to PSG, then Barca have one chance to get Hummels. Every game he plays, his price goes up. One more season in Dortmund will mean one more season where other big clubs could suddenly have the need for a new defender. I guess it's now (this summer) or never
The problem with our directors has always been the issue of slow reaction to amazing talent. I can't believe Zubi and the scouting department can concentrate only one transfer at a time. I mean yes, Zubi probably has to negotiate with Valencia for Alba, but I'd figure there would be some staff monitoring the likes of Hummels as well.
