Interested clubs face a race against time if they're to sign Benfica whizkid Gonçalo Guedes.
The 17 year-old winger has been likened to Bayern Munich star Franck Ribery and is the subject of enquiries from the German giants and Arsenal.
Guedes' current deal runs to 2019 and carries a buyout clause of €30 million. However, that option jumps to €50 million when he turns 18.
Fichajes.com says Real Madrid and FC Barcelona are also chasing the teen, along with Manchester City and Manchester United.
Guedes turns 18 on November 29.
