It's a tough question to answer. I'm waffling between the two this year as I think they've both been a bit more useful than some give them credit for, but they've also both been quite disappointing.
I will say, that if Medina can turn a corner next season, that his disappointments for this season become a bit more bearable.
If this really was Villa's last season here, then investing in the future when we had a win now team that needed another scorer is a HUGE FUCK UP. Even if he turns a corner next season, it's too late. We should have signed a 1 year DP like Zlatan in 2018, and after taking this as far as we could, get the young kids to develop in 2019.
