I'm guessing its from retired players only therefore no Messi? Have to say a midfield of Rijkaard, Zidane, Figo and Giggs would get raped in midfield by the current Barcelona side alone.
Edit: Definitely needs a Matthuis or Beckenbaur in there somewhere.
There is only one place Messi could take, and that's Maradona's given Baresi put up a 4-4-2 or a 4-4-1-1. Messi is not better than Maradona.
About that midfield getting raped... I would hope you're joking, but I sense you are not.
Regarding that team; I think it's the best xi I've seen an ex-pro put together given it actually has balance with top players in their best positions barring Zidane and Maldini, but even then, it looks like a proper, functional xi who would cause the opposition no end of problems and do a good job on the other side of the ball.
The defensive end is the area most of these ex-pro xi's usually make a mess of in their fantasy xi's. Baresi was a defender, so I'm guessing he built from the back where I reckon as it's usually midfielders and forwards asked to do these kind of things, that they start from their position or thereabouts and fit in all the best players they can, logistics be damned.
