Rapid Vienna midfielder Yusuf Demir is drawing attention from Barcelona, Manchester City, Manchester United, Bayern Munich, and Borussia Dortmund.

Demir, who won't turn 18 until June, is currently signed at Vienna through the 2022 season.

Barcelona are seen to have an advantage in signing Demir due to his admiration for Lionel Messi.

Demir could command up to $18 million in the transfer window.
