Sneijder, Robben, Ribery, Totti, Owen, Gerrard, Rui Costa, Pirlo, Seedorf to name a few players who definitely should have won for incredible performances in the CL except for Owen and Totti who didn't see proper CL action.
Not SINGLE one of those had a legit chance except possible case for Sneijder thats already weak (he wasnt even the undisuputed best player in his team lol, mediocre league season, good CL and WC), and Totti perhaps if he ever actually won anything while players as good or better were leading their teams to throphies while he wasnt (which year would you give him?). Totti was a genial player, if he wanted Balon d or chances, he should have left Roma. Then he could maybe get one like sheva and Nedved did.
Owen already won, and that in itself was questionable because Raul was better that year.
Most of those you mentionned werent even clear cut best players at their position for most years (some of them not even the best for their teams, Seeforf was rarely best player in his team, mostly a top 5 midfielder in Europe). Ribery in particular was an arrogant asshat for even thinking he is in Messi and Ronaldo's year for one top level year.
Pirlo could have a chance for 2006 balon d or if Cannavaro didnt get the award for being a charismatic leader, that was his only chance in Pirlos career IMO. He was the best italian player for me that world cup.
How do you even mention Rui Costa? He can legit be considered semi-flop for Milan, he wasnt consistent enough and was considered underwhelming in pure top player impact, that they had to get Rivaldo and Kaka to get a real impact AM to get title chances.
