Tello is different to Pedro and Alexis, but I wouldn't say he was less talented than either and if his experience was the same as the latter I would bet he'd be better than both.
Fact is he struggled to dribble past players in the charity match with Messi and he lost the ball a lot without really doing much with it, Neymar will not end up like Alexis he is far superior.
The sad thing is Brazil used pretty similar tactics to Bayern and they complete nullified Spain to a point where is was just as embarrassing as Barcelona vs Bayern. Teams are learning that both Barcelona and Spain aren't as mighty as they first appeared to be with the right players and tactics.
Our players seemed scared of Bayern, even when the first leg started, which I can understand considering we were without Messi. I remember him performing against Real Madrid and Milan, he just wasn't given the opportunity in most big games.
