What the shit are you talking about? Costa provided no threat all season. He was creating zilch.
Mandzu has 3 assists in the last couple months, so that’s hardly nothing. He also was fantastic winning balls just two games ago against Milan, helping close out that win. Add in his bicycle kick that forced a great save from Reina, and the pass he squared to Kean for a great chance in the box when it was still 1-1. Hardly nothing.
But yes, Mario has been poor. But Mario has 3 years of fantastic clutch performances in big matches for Juventus behind his name... Costa has 4 great months to finish last season, and a disastrous 7 months to start this year. Of course he’s going to get bashed, we all had high expectations for him.
Sandro is bashed easily as often for his poor form. Khedira is bashed 10x more. Dybala is bashed all the time right now. And so is Mandzu contrary to your opinion, even if a few of us generally defend him. It’s not some exclusive bashing of “poor Costa” thing.
