It is true that Barcelona are going to be in search of a new striker. But I don't think that it should be Aubameyang. He is 32 years old now and quite old for them. I think that Barcelona should be looking for younger and talented strikers. They have a very young team now and it would be better to add not a very old striker to the team. They can still look for experienced strikers but their ages can be less than this to be beneficial for the team for long years.
Right now Barcelona need good players at low prices, and Aubameyang could be a very good opportunity for them.
I say this because, regardless of his age, Aubameyang is a very good player, an excellent scorer.
And Barcelona want to take advantage of the player's current plight at the gunners, where he lost his captain's armband and was put on the bench after breaking club regulations, to try to bargain.
