Ten of last year's World11 return to make the 55-man list, with Real Madrid CF the most-represented club, seeing full 11 players make the cut.
FIFPro have announced their top 15 forwards in world football, as voted for by fellow professionals and there is a place for both Salah and Mane.
The final list of 2018 FIFPro world 11 will be announced on 24 September at the Royal Festival Hall in London.
However, only three midfielders make the all-star side, along with a goalkeeper, four defenders and three attackers.
Mane, a Senegalese player, has been a regular inclusion for Liverpool in the last season when they reached the final of Champion Leagues and lost to Real Madrid.
The two sides have a lot of players nominated by Federation Internationale de Football Association to be in their team of the year, more than any other clubs including Man City and PSG. Andres Iniesta, who left Barcelona for Japan's Vissel Kobe, is on the list for the 12th year in a row. He has already won nine World XI awards, including last year's.
