Gareth Bale, Sergio Aguero and Alexis Sanchez have missed out on the shortlist for attackers in the FIFA FIFPro World 11.
Sanchez has struggled for form since joining Manchester United from Arsenal in January and has not earned enough votes to make the final 15.
There is also no room for Bale, despite the Real Madrid forward scoring 21 goals in all competitions last season, including two in the Champions League final.
Zlatan Ibrahimovic misses out for the first time in 12 years, as do Manchester City duo Aguero and Raheem Sterling.
Gonzalo Higuain, who scored 23 times for Juventus last season in all competitions, is also not included, but Mario Mandzukic returns after a five-year absence.
Liverpool's Mohamed Salah and Sadio Mane have been included for the first time, while Cristiano Ronaldo is in the final 15 for the 14th year in a row.
Earlier, Arsenal's Mesut Ozil and Bayern Munich's Thiago Alcantara were two of the big names to miss out on the top 15 midfielders.
Manchester United duo Paul Pogba and Nemanja Matic were included, as was Andres Iniesta, who left Barca for Vissel Kobe after the end of last season.
AC Milan's Leonardo Bonucci did not make the final list of 20 defenders, which included eight debutants, including Yerry Mina, Virgil van Dijk, Joshua Kimmich, Benjamin Pavard, Dejan Lovren and Kieran Trippier.
The five goalkeepers shortlisted were Gianluigi Buffon, Thibaut Courtois, David de Gea, Keylor Navas and Marc-Andre ter Stegen.
The final World 11, comprising the keeper, four defenders, three midfielders and three forwards with the highest number of votes, will be announced at the Best FIFA Football Awards in London on September 24.
