The son of a Brazilian legend has joined Burnley after leaving Spain to sign a professional contract at the Championship side.
Burnley have been keen to invest in young potential talents around Europe as the 19-year-old travelled to England at the start of the week and signed a two-year contract at the club.
His departure from Barcelona comes as the creative forward leaves the LaLiga club where he struggled to make an impact at their La Masia academy.
Joao Mendes is now expected to link-up with his new team-mates, but it is yet to be seen whether he forms part of Scott Parker's first-team plans or will instead join Burnley's youth teams.
