It's always a dramatic and bizarre moment when an outfield player goes in goal.
First comes the panic, as fans start to wonder who will take one for the team. The chosen one then chucks on a spare goalkeeper shirt - which is usually far too big - and slides their hands into some sweaty gloves before facing the daunting prospect of making saves.
Several outfield players have experienced this during their careers - such as Kyle Walker, Harry Kane, John O'Shea, Rio Ferdinand, Phil Jagielka and John Terry. The latter famously donned the gloves in a Premier League game in 2006 - but it's not a happy memory.
