I think Aubameyang still has got his touch and pace right but I would agree on that he wouldn't make much of an impact signing but I also might be wrong. We saw how well he was at Barca if he can continue that same thing then I think he will be the most goalscorer for Chelsea this season but well let's see about that as it depends mostly on Tuchel and his plans.
One problem is solving the scoring problem, the other solving the issue of not conceding. Because Chelsea so far are very poor in Defending, but let's see maybe FOFANA will be able to help them solve the issue. Because even if Aubameyang keeps scoring it won't help team. It will just be a case of Man United last season where Ronaldo has bunch of goals but at the end nothing to show for it in terms of league standings
In this case, especially this season, Tuchel is facing increasingly difficult problems because indeed they still have many shortcomings due to some of their core players leaving and the average players who come out are players in attack and defense, it is clear that even if there are new players, this will still happen. It's a bit difficult I think because new players obviously need to adapt.
But on the other hand, at least with a name that is quite well known and their individual skills that are indeed good might be a little better.
It may not be visible now but when they find their rhythm things will change I think for Chelsea.
