Van Persie handed £10m loyalty bonus if he remains at United for duration of contract



Robin van Persie stands to earn an extra £10million on top of his mammoth £250,000-a-week wages at Manchester United - just for staying at the club for the duration of his four year contract.



The cash bonus will be spread throughout his stay at Old Trafford and does not take into account any bonuses that the 29-year-old will earn if United win the League, FA Cup, League Cup or the Champions League.



Many inside United, including chief executive David Gill, questioned whether a £64million investment in Van Persie - a £24m transfer fee plus his wages for four years - was prudent.



Cash boost: Van Persie will earn an extra £10m during his stay at Old Trafford

Ferguson went to unprecedented lengths to push through the deal for Van Persie, believing it was the only way for him to leave a fitting legacy when he retires aged 72 in the summer of 2014.



There will be no resale value on the Holland striker to help ease the club's debts, which run into hundreds of millions of pounds.



But having given the Glazer family his public support over the years, against the wishes of many United fans, the owners gave Ferguson payback by bankrolling the deal.
