If you had a choice of bringing Ronaldinho to Chelsea in 2004, would you have taken it? I would have, but Jose Mourinho wouldn't and didn't. He was asked if the Brazilian was someone that he would want in the team, and he respectfully declined.
I guess he had his reasons, but having the opportunity to sign Ronaldinho and not taking it feels like daylight robbery. He is respectfully named as one of the footballing gods for a reason, alongside big names such as Pele, Diego Maradona, Ronaldo Nazario and Johan Cruyff.
The Portuguese manager had other plans which weren't so bad, but could we have saved years of Champions League pain if Mourinho had just said yes? Hard to say, but what I can say is that his reasoning would have possibly made us miss out on Eden Hazard.
