Manchester United have reportedly included a sell-on clause in the deal to take Romelu Lukaku to Inter Milan on deadline day.
The Manchester Evening News reports that United have also included a clause in his contract which means that they will recoup a percentage of any fee Inter Milan receive if they sell him in the future.
The Red Devils took a similar action when selling Wilfried Zaha back to Crystal Palace in 2015, a move which could prove to be lucrative as they are due 25% of the in-demand winger's transfer fee.
Lukaku also had a sell-on clause in his contract which took him to Old Trafford from Everton, meaning that the Toffees will receive around £5m from the Inter Milan deal.
The player scored 42 goals in 96 appearances during his two seasons with United.body check tags ::
