MELBOURNE (Reuters) - Real Sociedad have signed Australia goalkeeper Mat Ryan from English Premier League side Brighton & Hove Albion on a two-year deal, the La Liga club said. After four years at Brighton, 29-year-old Ryan returns to Spanish football, having had a three-year stint at Valencia from 2015-17. Ryan's deal includes an option for a one-year extension, Real Sociedad said. "I will work hard and I can't wait to get started playing for the team," Ryan, capped 61 times for Australia, said in a media release.
