El Douglas is going to be an instant hit, we fans are gonna love him.
Until we'll hate him ofc.
That depends what does one expect out of him.
Douglas has flaws, and if it shows in the late CL stage, even if he does great in Serie A, I expect the common backslash a player gets when it happens.
People will not look at what he globally achieved, just how he failed during one or two games.
I don't point fingers at anyone, it's like that everywhere about most signings, unless you buy somebody that is sure to do good in almost every important games. It's rare.
It's also sad, because people in general tend to easily forget what was good.
I am not a fan of Costa, but since it seems almost done, let's hope he performs.
