I would say our midfield and defense need to be looked after much more than our forwards. Iniesta and Rakitic are only world class CM's we have. Roberto is a good back up but if one of them gets injured, we might as well pray. Just looks like Bayern did good business getting Sanches right away.
I disagree. Defense and attack must be clear priorities, which, luckily, Lucho knows.
Also, we've never had world class players in every single backup position. Solid squad players we have, though, and I'm probably going to be called out as being overly optimistic in this regard, but I still feel that Sergi Roberto, Rafinha and Denis will be able to contribute more than the Pogba or bust brigade will have us believe.
If he turns out a great player, then yes, Bayern will have done great business, but that has got nothing to do with us or our current situation.
