Xavi worked quite efficiently and quickly because the certainty of Busquets leaving was final for his decision and of course with Gundogan in their squad it was clear this would have a positive impact.
Gundogan's leadership spirit and calmness need not be questioned even though it is impossible for him to immediately become captain but still with him and the experience he has it is clear that this is very good for Barcelona....
Xavi has a long history with Barcelona and he is also very familiar with the characteristics of his game throughout the game. so when he comes back and tries to fix Barcelona from the bottom he knows quite a lot about what's going on in Barcelona, what needs to be done and also various evaluations for that. we'll see how Barcelona after Ada Xavi they were able to get up and have started to approach Barcelona's very good style of play and won La Liga last season. and this is not easy because we all know that Barcelona competed like that for a few early days so they lacked a lot of points.
