He may have failed to make the grade at Old Trafford, but in Brazil everyone has the same opinion of Kleberson: that he's a top player. He's resurrected his career at Flamengo and whilst he may be frequently afflicted with injuries, he bounces back stronger every time. Compared to fellow Flamengo player Adriano, Kleberso is significantly more likely to make he squad for South Africa. Dunga values hi highly and he's a fulcrum of the Flamengo side.
Speaking of big name players in the Brazilian league that have flopped, you can't forget Cicinho who has been an absolute embarassment at Sao Paulo. Heck, Robert Carlos has been very poor at Corinthians and he looked poor last season at Fenerbahce, it's as if he's forgotten how to control the ball and has been a massive flop (He's been sent off twice and in tose gams, against Santos and Palmeiras, it's the only time that he's hard a significant part to play).
