The deal would see United pay an initial fee of €55million plus add-ons, which could see the deal rise to €80million, reports Sky Sports.
As well as the initial fee, Sporting would receive a further €10million from United if Fernandes achieves what are considered easily achievable targets.
And an additional €15million if Fernandes achieves what are considered more difficult targets – including winning the Ballon d’Or.
Bruno Fernandes remains in Lisbon considering his next move – joining Barcelona, via Valencia in La Liga or a move to Manchester United.
With both United and Barca offering deals acceptable to Sporting, it looks likely that Sporting will now allow the player to decide his future. Clearly a decision is just hours away.
Barca are thought to have offered a slightly bigger fee for Fernandes – however, a significant part of that figure would not be paid until the summer.
