Thiago Silva is a very good central defender, currently one of Fluminense's best players, and part of this year's Brasilian Olympic football squad. An agile and smart centreback, very good at intercepting passes and man-marking. Thiago played as defensive mid in the youth divisions, but it was after he moved to central defense in 2004 that he began to shine on a national level.new name today...a brazilian defender from fluminense, thiago silva...don't know if he is good...and not sure his age...

Thiago has his own website - in portuguese - where you can find pictures, videos and other stuff about him. There's also a profile page describing Thiago's career since childhood, and it mentions his failed transfer to Porto in 2004; apparently, the unfortunate combination of a bad injury and a pneumonia stopped him from showing his qualities in Porto, then he was loaned away to Dynamo Moscow and later Fluminense brought him back to Brasil (please note that the above info about his experience at Porto was all taken from Thiago's website, so I can't confirm its accuracy).
