Manchester United are monitoring the progress of former top transfer target Thiago Alcantara's younger brother with a view to a summer bid, according to The Mirror.
Thiago's sibling Rafa Alcantara is on loan at Celta Vigo from Barcelona, but remains a firm part of the Calatan giants' plans moving forward thanks to an impressive start to the campaign with the La Liga newboys.
The 21-year-old largely operates in a similar midfield area to his more famous brother, who Manchester United failed to sign last summer as Bayern Munich won the race for his services.
United are casting their net far and wide in search of new recruits during the close season, with Rafinha's development being monitored closely as part of a concerted effort to overhaul an under-performing squad.
Rafinha, as Thiago's younger brother is more commonly known, has largely operated in a deeper midfield role this season at Celta, contributing three goals and five assists in 23 matches.
The starlet has represented Spain and Brazil at international youth level, switching allegiances back to the country of his birth Brazil in late 2012.
United will face a fight to persuade Barca that the youngster has no future at the Camp Nou though, with La Liga's reigning champions grooming the starlet to join their conveyor belt of midfield talent next season.
