Real Betis and Spain Under-21 star Junior Firpo has long been touted as the most likely left-back signing for Barcelona, but the Andalusians are likely to demand close to the rising star's €50m release clause - amid supposed interest from the Premier League - making him an expensive addition.

Mundo Deportivo (MD), claim that as an alternative Barcelona are now investigating the enticing option of Bayern Munich's David Alaba. However, that suggestion is totally rejected by rival Catalan football daily SPORT.
The 27-year-old Austrian has been a key performer for the Bundesliga-dominating Bayern in recent years but may see his role changed or even diminished following the arrival of Lucas Hernandez in Bavaria for a club-record fee of €80m.
