The Sunday Mirror says United have already paid Arsenal £24m for the Dutch striker – and van Persie’s basic wages of £200,000 a week at Old Trafford over four years will be worth £36m.
He will also be paid £10m loyalty money, spread over the length of his stay. And there are bonuses to be added - which tally up to a stunning £70 million outlay from United's money men.
A senior source at the Emirates said: "It did not come into the equation that it was Manchester United. They offered the asking price.
"And if Robin had stayed for this season, he could have joined United - or any other Premier League club, come to that - for free next summer and we would have got no compensation."
And the source added: "Arsene Wenger will get every penny of the fee for his own transfer kitty."
