"I've been extremely impressed with his knowledge, intelligence and passion for the game and the club," Birch told the Swans' official website.

"Swansea City has already seen the benefits of his input with the footballing appointments we have made so far.

"Having been a former player here for so long – and respected so highly by the fans, staff and players – it made perfect sense to get him involved, initially as an advisor.

"Since then he and I have worked really well together, and he has struck up a great working relationship with Steve."

Britton made 536 appearances in all competitions for Swansea during a 16-year spell as a player after arriving, initially on loan, from West Ham in 2002.

He helped the Swans escape relegation from the Football League in 2003 and went on to play in all four divisions for the club after winning three promotions to reach the Premier League in 2011.

Britton has had stints on the coaching staff under former manager Paul Clement, spent two games as caretaker manager before Carlos Carvalhal's appointment in December 2017 and had one season as club ambassador.
