Brighton manager Gus Poyet told the club’s official website of his delight at being able to bring a player with such extensive international, European and top-flight experience to the Championship club.
He said: "It's difficult to say how I happy I am because it's not easy to get top-class players. I'm absolutely delighted to have Wayne with us. He's been one of the top three left-backs in this country for many years.
"There were a lot of things that had to come together to make it happen. Firstly, David Platt has been great at Manchester City and then Wayne and his agent have helped a lot too.
"It was not an easy one to secure, but this is what we want at this club. He's a quality player with lots of international experience.
Potentially one of Bridge’s first matches for Brighton will be a pre-season friendly on August 4 against former club Chelsea, where he won the Premier League, FA Cup and League Cup during a successful six-year spell.
