Cameroonian duo Jean Marie Dongou and Macky Frank Bagnack have both signed new long-term contacts with Spanish champions Barcelona.

The 18-year-old pair are both highly-rated at the Camp Nou, with Dongou a regular member of the first-team squad this season.

Bagnack is yet to make his bow for the Catalan outfit, but has been tipped to make the breakthrough in Spain.

"I am very happy at signing my new contract. This is a very important day in my career. I'm very excited to continue working and improving," Dongou told reporters at a press conference.

Both deals will run until 2017.
