Ozil was sold because they bought Bale and Isco in that window, Modric in the window before, and Kroos the window after. I think we can all agree that Mesut was a luxury piece for them.
They sold Hakimi due to finances from Covid, not that they wanted to. Though they did buy Mendy around that time who was hyped as one of the best players in his position at the time.
Higuain was sold because Bale practically took his spot and he was never really that good to begin with.
Kovacic, I can agree with you on that.
Mega disagree, Madrid is in the market to never lose on a deal. They might overspend and sometimes buy rubbish players (James), but they don't lose on deals when selling them.
