Do u think Louis van Gaal is doing bad?

Bayern Munich did not had to buy Gomez, they already had Klose and Toni, Olić. Now Toni wants to leave. Also, buying Robben was unnecessary, he always injures, and they already have Schweinsteiger ,Baumjohann,Sosa,Ribéry, Altıntop. Also, Luio was the best defender for Bayern.
