Groningen revealed a few days ago that Barça are interested in the midfielder. They also revealed that negotiations had begun regarding his move to the Camp Nou.
According to 'De Telegraaf', the agreement between the clubs has been confirmed. However, his signing will not be for 2.5 million euros as had been speculated.
According to the aforementioned media, Barça will pay around 8 million euros to sign the 18-year-old midfielder.
Reis would arrive at Barça from July. The club's plan is for the youngster to play for Barça B, but would travel with the first team to Japan to tour with them.
The contract between Reis and Barça will span five seasons. It remains to be seen as to whether the clubs release an official statement.
José Mari Bakero, responsible for Barça's professional football training, had been following Reis for months. Finally, it seems that Barça's visits to the Netherlands have paid off.
