I didn't expect this to happen, Barcelona especially the manager doing a good job to sell Aubameyang to Chelsea. I'm not sure Xavi make the wrong way, but from what I look how effective Lewandowski is on the front, Sold out Aubameyang is a great step for Barcelona back to what they did before. I don't care if he is back like on Barcelona, but if he stays on a good hand, Aubameyang could be better in Tuchel's scheme, or not possible for Chelsea to create again Lukaku v.2
For now, Barcelona must sell Aubameyang since they need to register Kounde, nothing wrong with this. But I'm a bit unsatisfied since Barcelona signed Lewandowski although they have Aubameyang who played well in the last season. This means Barcelona didn't appreciate what Aubameyang has done for the club. I don't blame Xavi, it may be the decision made by the president club or another person in Barcelona management. However, on Aubameyang's side, it is the right decision to leave now because he will sit on the bench if he stays. Since Aubameyang ever played under Tuchel's management, I am sure he will play better in Chelsea.
