Barcelona have signed a collaboration agreement with Boca Juniors.

Jordi Mestre, FC Barcelona youth football director, said that this "project requires time and patience".

He said: "it's a big day for FC Barcelona because the club has relied on our youth system for a long time and the truth is that it has paid dividends. We have club players that are world champions and that's due to many years of work.

"Two powerful clubs are betting on football in a decisive way. I hope that it [the agreement] is successful, it's a project that requires time and patience. Evidently, the results will come if the work we put in is good. For us it's a satisfaction to be able to share this project with a club like Boca. It's very exciting that the model that we've been working on all these years can be shared and used."
