I personally wont be dissapointed at all if thuram goes, better now than another season with the old veteran, he hasnt got too much in his tank, we need some fresh players and we can only do that by getting rid of the old. Just a comment about this rumour however...Arsenals right flank is pretty much strong as it is (eboue) also his centre backs are marvelling (toure, senderos). Clichy also looks like a good backup. Cambell may not have been good this season and possibly with him, cygan and laauren leaving it only then makes sense of thuram being chosen as a target. Even so if that is the case then Thuram will have to play part as a sub player, which i dont believe he may be that pleased about.
Nevertheless it all depends on how much we may get for thuram now, if we get rid of him next season will we really get as much? or can he really provide solidarity at the backline consistently for us next season.
If we do get rid of him then I believe pepe would be the ideal candidate to replace him, his physically as strong, young and much faster, although not prooven as much as thuram for obvious reasons it would be ideal however to bring a better fresh line up to the ageing centrebacks. Of course I wont argue with having gallas too.. either way there are many more better solid centre backs in the world and im sure they wont cost us too much of a fortune.
