What, Eboue plays exactly nothing at all like Chico, nothing, its not even comparable. Chico, stands offside and hopes to get a pass in behind and called onside(yes bit more to it but thats most of this game). Eboue, fantastic freekicks, corners, fantastic crossing, runs with the ball, "does" players, great throughball, great passing, bags of pace, stronger than his frame would suggest. Creative, defensive, workrate, good finishing, he's really good at every part of the game, in no way does he just sit on the back line trying to get in behind.
Eboue is very defensive when required, he's one of the hardest working wingers in the league and consistantly gets back down the wing to make tackles, which he's also good at. Considering Valencia defensively was probably your single worst player against Barcelona, and Park did pretty much smeg all defensively all match aswell I wouldn't count on them being named in a "defensive" lineup.
Running back a bit and running back a bit and actually having the ability to tackle and know where to be, how to mark well and how to be effective are very different things.
