I am not an expert on Barcelona situation but Alves had a pretty bad season the previous year and a bad reputation for revolutionizing the dressing room , plus he is 32, so I imagine that Barcelona wanted to reduce wages and the number of years of contract . His performance improved and certainly the opinion of Messi had much to do in the club trying an understanding. In this case I think the situation is more complicated, Ramos 's relationship with the president is broken and has been very noisy with his brother leaking everything to the press, besides according to the press he feels hurts in their pride.The alves situation threw me off. You see this differently to alves' antics to get an extension?
In any case ,maybe you don´t like your boss, or the way how he runs the company, but that is not a reason to quit your club for a decade. He is not the best paid but 7 million a year is no disrespect in my opinion.
Madrid is not going to offer 10 after tax, maybe 7.5 or 8 but never 10.
