When questioned whether Bayern midfielder Martinez could be one of the new arrivals in the summer, the Bilbao president insisted that if the club's transfer committee felt that it was a priority, then the board would be happy to oblige.
He added: "If it is a consensus strengthening in the sports commission the board will do everything possible to do so. Athletic can pay 20 million for Javi Martinez without any problem.
