If one of the alternatives (Montoya or Douglas) were any good and would shine in training, Dani wouln't start every game. The problem is they both suck even more than Alves.
We have a huge black hole in our squad at RB, and that is entirely on dumbass Zubi.
The alternatives are Adriano, Montoya, and Douglas.
Douglas shouldn't even be playing top flight European football, so I'll give you that, but Adriano and Montoya haven't received more than 90 minutes apiece as RB so there is seriously no way you can claim they're worse than Alves. Dani boy has been so incredibly dreadful that it's not like giving one of our alternatives a chance to do better would hurt is the way playing an alternative in any other position would.
