Tata has some big challenges. Some of the biggest involve how to evolve the roles of his biggest stars.
The good news is that the big personnel improvement should lessen Messidependencia. The team now has a second big-time goal scorer. We know that it takes at least 3 defenders to have any chance against Messi. It also takes at least two defenders to cover Neymar. The best play for this season will be the pass from Messi to wide-open Neymar, or the other direction. I think Neymar will be on the field every minute Messi is on the bench. It will be interesting to see if he stays at LF or slides over to CF. This is a big improvement on the strike force without Messi of last year.
Neymar needs to take over all the corner kicks and free kicks from the left side. Can Xavi deal with this? Does Tata have the guts to make this happen?
Cesc will have his chance this year to play as much midfield as he can handle. I think he might get more playing time than Xavi. The offensive midfield rotation of Iniesta-Xavi-Cesc is the strongest in the world, regardless of which pair starts the biggest games. Can either Xavi or Cesc handle missing a lot of the biggest games?
Regardless of which CB gets added, Barca will not have the size and strength to defend corners. There is no way to coach your way out of this, it is brutal physics.
Last year, I though the coaching staff was stupid to keep trying long corners. Face the facts, switch to all short corners.
Some of Tito's worst mistakes last year were sticking too much with the big stars. Playing Messi and Busquets injured was disastrous. Thiago left because Xavi and Iniesta were overplayed.
