Not boasting at all. Simply pointing out that if young players are good enough, then they can benefit any team, no matter their age. We signed and played Gabriel Jesus when he was 19 and Real Madrid signed and played Junior when he was 18.I don't see how that's relevant to my post at all. The point is that clubs like Real Madrid don't need to concern themselves with signing 19 year olds from Sao Paolo and hope they come good when they can sign them as Ballon d'or winners who walk into the side 5 years later..
Also given Kaka played 10 minutes in that world cup in a dead rubber group match, I'm not sure why you're boasting about him being a world cup winner.
