Here is the difference though my man.
Vidal and Coman wanted to leave. In fact, Vidal openly recruited Coman in the press for him to come to Bayern just days after he signed for them. And let's not forget that Juve got 40 million for Vidal. Just because us internet sporting directors valued him at more than that, doesn't mean that teams were lining up for a player that was A) coming off an injury plagued season, and B) went and nearly got himself and his family killed in the off-season. Not the first time that he had an alcohol related incident. Real Madird even went out of their way to release a statement saying that they were no longer interested in him.
As far as that situation is concerned, I tell other Juve fans to think about this for a moment. If it were Juve that were buying Vidal from Bayern, given the circumstances that had played out, and the pricetag was 40 million euro, how would everyone have reacted? We would have lost our minds.
Cuadrado was a free loan, and Chelsea insisted that there be no option to make it permanent. It was a no lose situation for Juve no matter how you look at it. They paid nothing for him, he provided some good moments for us, and now that is it. He goes back, without any sort of performance or appearance based obligation tacked on. If they can negotiate something, great. If not, well, thank you for the 1 year that you were here.
