Foster's promising career with Manchester United was stopped in its tracks by a cruciate ligament problem that needed surgery on his right knee last summer.
But after the best part of a season on the sidelines, the 24-year-old is back and was desperate to play in United's reserve team against Liverpool at Warrington last night.
A source close to Foster told the Daily Mail recently: "Ben feels he is at the age where he wants to stake his claim. His priority is getting fit, but he feels he is doing that. After that, he really wants to make a start on his career at United."
