The 38-year-old started his career at Racing Club Warwick, before spending four years at Stoke City, where he was sent out on loan each season.
After impressing while on loan at Wrexham, Sir Alex Ferguson brought Foster to Old Trafford, and the former England international accumulated 12 Premier League appearances for the Reds between 2005 and 2010.
Foster spent his first two years at United out on loan at Watford, the club where he now plies his trade, following spells at Birmingham City and West Bromwich Albion.
As you will hear when you listen to Foster's episode of the UTD Podcast - available now in the United App – he shares his experience of training with Edwin van der Sar, and opens up about the pressures of playing for a club like United.
