The former England midfielder Owen Hargreaves has joined Manchester City on a one-year contract after leaving English premier football league rivals Manchester United, as a free agent at the end of last season.
The injury-hit 30-year-old, who has won 42 caps, posted videos of himself on YouTube carrying out exercise and mobility drills to prove his fitness.
Hargreaves had played only five minutes of first team football for United in his last three seasons and left the Old Trafford club having made just 39 appearances in four years, with his time there blighted by chronic tendinitis in his knees.
