#1 Ronaldinho

Real Madrid's decision to repudiate Ronaldinho is one of the worst transfer decisions ever taken. And it's not their rejection alone, but the reason behind it is also more than just pathetic.
Apart from signing the players based on their quality, Real Madrid also make sure they prove to be a good marketing brand for the club. That's the reason why they rejected the Brazilian grandmaster -- because, according to Perez, he was too ugly! Instead of signing him, they went and poached David Beckham from Manchester United.
No disrespect to the Englishman; he was one of a kind, but certainly not in the same league as Dinho. Los Blancos will surely have incurred huge monetary gains by signing Becks since he was a global icon during his time.
But, when it came to 90 minutes on the pitch, Ronaldinho didn't leave a single chance in compelling Real Madrid to regret rejecting him. The wizard conjured a brand of football that made even his rivals adore and love him. Remember the Santiago Bernabeu ovation, eh?
Florentino Perez's alleged 'hatred' for black players was also highlighted by Iker Casillas's agent Santos Marquez, who accused him of selling the likes of Claudio Makelele and Samuel Eto'o because of their dark complexions. No need to mention how those two achieved a legendary status in the sport following their departures.
Beauty goes skin deep, Florentino. The sooner you understand this, the better.
