Ibra scored 21 goals in 41 games, even while adjusting to a new league, new team, new players, new style etc. Adriano hasn't been excellent but he's hardly their first choice starter and it's been just a year so it's difficult to label him a flop yet. Dymtro again, a fairly poor first season and then sold so difficult to judge. I understand your point about us having players not suited to Barca's style, but surely that will change if he's appointed since he will look to bring such players in. And regarding different tactics, thing is, he doesn't need to have a lot of aces up his sleeve, the quality of his team and their utter dominance over others in La Liga means hey get their way very often, not requiring drastic alterations.
