Sir Alex Ferguson is a reported fan of the young left-winger and his French scouts are understood to have watched him in action for Marseille several times over the current season.
And Barca are also being linked with the Ghana star.
Ayew told skysports.com: "It is fantastic to hear these stories, even if it's just through newspapers.
"I am delighted to be linked with two powerhouses of world football. It means I have improved.
"I have not got a favourite, I am just speechless!
"It would be a dream to join one of them, but I am living the dream here with Marseille as well and also looking forward to a strong finish to the season."
