Man Utd continue to track Romelu Lukaku despite the offer of an improved deal on the table from Everton.
The Red Devils maintained a discreet distance this summer after his father revealed their original interest.
Lukaku’s former club Chelsea are reportedly still willing to part with £65m to take the player back to Stamford Bridge.
United, however, scouts were on hand to see the 23-year-old score in last Friday’s 1-1 draw at home to Crystal Palace – his fifth goal of the campaign so far.
It’s understood the Merseyside club were aware of their presence and it will only speed up the current efforts to get him to sign a new five-year contract worth £100,000 a week.
Everton’s concern that he could end up at United is further heightened due to the player’s agent, Mino Raiola, who was responsible for taking Zlatan Ibrahimovic, Henrikh Mkhitaryan and Paul Pogba to Old Trafford this summer.
