Carlisle will hope that Dean Henderson becomes Manchester United's number one goalkeeper, as they reportedly profit each time he plays.
The 23-year-old joined United from the Cumbrian outfit in 2011 when he was just 14-years-old.
Henderson is number two at Old Trafford to David de Gea and has made 13 appearances this season - mostly in cup competitions.
The Sun have now reported that each time Henderson plays, the League Two outfit pick up £10,000 on the back of the deal they made with United when he was 14.
