Pic: Stilyan Petrov plays his first Aston Villa game since leukaemia diagnosis

There are few stories in football more inspiring than that of Stilyan Petrov.

The Bulgarian midfielder was diagnosed with leukaemia in March 2012, and retired from football after fighting to beat the disease. But four years on, Petrov has returned to the game, with former club Aston Villa welcoming him back into the squad for the 2016/17 close-season. And the 37-year-old stepped out onto a football pitch in Villa claret and blue for the first time since his diagnosis, playing 45 minutes in a pre-season victory over Austrian club Gak 1902. https://twitter.com/AVFCOfficial/status/751838999505956865 Villa won the game 8-0, but the scoreline took second billing to the return of a club legend. Petrov made more than 200 appearances in his first Villa spell, having also played for Celtic and CSKA Sofia earlier in his career, and was club captain when the Villans finished sixth in the Premier League in the 2009/10 season. Fans have greeted his return with a mixture of shock and pride, as few ever expected him to return to the game, even after beating cancer. https://twitter.com/ChrisMNee/status/751841903784624129 https://twitter.com/7500toHolte/status/751840395395465216

Supporters of other clubs also chipped in with well-wishes - even those of rivals Birmingham City.
