The president of the Aviron Bayonnais, Yannick Bru, explained that he is "Very happy with the extension of the contract with this great professional, a great worker, who is a model. Mariano has been perfectly integrated in Baiona for two years, and he is a leader. He has excellent values, and serves as an example for the young people of the club, and so it only made sense to extend his contract with us.”
