Sport says Farinas was one of the most promising talents at Villarreal's excellent youth academy.
The midfielder has huge potential and he showed that in the Liga Promises tournament which took place in June.
After a few meetings a deal was made for the youngster to join Barça.
He has already signed a four-year contract and will live at La Masia. If there aren't any changes in the next few weeks, Fariñas will form part of Alex Urrestarazu's Infantil A squad.
