It's very sad to say it, and that's just my opinion, but the Xavi , Pirlo, Lamaprd, Gerrard type of players are gone for good now, with Xavi being the ultimate example amongst them.
It will all depend on the philosophy we want to implement for the upcoming 3-5 years.
We'll most certainly need a top technician and tactician for our midfield by 2016, and Denis Suarez isn't one... for the moment.
Kroos would have been the best replacement for Xavi available, but he would not accept playing less than 3.000 minutes and him coming to Barcelona is as unrealistic as it gets.
