Lucho has shown some disastruous gaps in understanding the basis of football. He basically repeated the same mistakes that Galactico Madrid did. Signed superstars in attack and filler in midfield, because the money were spent on big transfer with insane wages, so logically, paying those money for those players meant we had to cut costs in midfield. That's why Kroos for example wasn't signed, but Rakitic was. Rakitic was less expensive and his wages were significantly lower probably.
Football time and time again reminds teams that football is about the team, not about which side has more superstars. It's time to sack the idiots that went this way and bring us back to the drawing board and actually building a team built on some clear foundations.
