Sylvain Marveaux appears likely to return to Newcastle next summer as loan employers Guincamp cannot afford him.
Melbourne City loan striker David Villa is set to return to New York, according to reports.
The 31-year-old right-back came through the youth system with Los Leones and is currently playing in his 11th professional season at the club.
"The Athletic Club and player Andoni Iraola have signed the renewal agreement whereby the player will remain with the red and white until June 30, 2015," read a statement on athletic-club.net.
