Everton are due a windfall as part of Manchester United's planned sale of Romelu Lukaku.
The Belgian is said to be keen to leave Old Trafford and wants to join Inter Milan.
Even though United are yet to receive a bid, Lukaku is said to want a deal to have been completed before the end of the month.
And should he get his wish, Everton will get £5million of any fee United receive, says the Liverpool Echo.
The Blues inserted a sell-on clause when selling the forward themselves two years ago.
