Menez, Totti and Vucinic are all technical players and the latter two are very intelligent football-wise. I don't know what could Menez wish for there. Then add Pizarro and you have 4 technical players. One Taddei or one Perrotta don't change much when the others there are Totti, Pizarro and Vucinic.
Not even close to the pure talent Juve has (which is actually only Del Piero).
Not many times you can see them playing. Far too many times it happened to see only Vucinic and Menez, or just Menez and Totti.
Roma keeps him on the bench many times and subs him instead of Mirko since they are scared of taking Totti off. But when the French guy starts going forward, there is nobody around him and on the flanks there are those brainfarts like Pepe.
Add to note that Del Piero plays on a much higher level than Totti nowadays. Totti might score more but he can't create anything and IMO he's playing piss poor for quite a while now. Watch him and you'll see how slow he is and how little he contributes nowadays. He has proven that many times this season.
