EgyptianPlayers.com reports the 20-year-old Egyptian has been invited to trials with English Premiership club Everton starting on Tuesday.
Paris-born Mansour signed a two-year contract with French outfit Auxerre in 2010. He was a regular with their B-team but decided to part ways with the club after they were relegated last year.
Stoke City have also offered the promising Egyptian keeper a trial.
Mansour has made four appearances with Egypt's U-20 national team.
