Harry Kane would be ready to end his contract with Tottenham.
SunSport reported last month that Manchester United were confident of signing the Spurs striker if the north Londoners do not secure a Champions League spot.
Kane, 29, has 14 months left on his contract with Tottenham and club figures are increasingly wondering whether he will sign a new one.
According to the Telegraph, the English skipper would consider reviewing his contract at Tottenham before leaving on a free transfer.
Man United are reportedly ready to offer him a £100,000 bonus on his current £200,000-a-week deal with Spurs.
While players who leave on free transfers can often charge huge sign-up fees.
Red Devils fans chanted ‘See you in June’ to Kane during last Thursday’s 2-2 draw with Tottenham.
United bosses were comforted after a positive meeting with the striker’s representatives through intermediaries last month.
But they want to get a deal done quickly and avoid a long summer transfer saga.
The Red Devils have had difficult negotiations with Spurs chairman Daniel Levy in the past when signing Dimitar Berbatov and Michael Carrick.
Should Levy fail to accept an offer before the start of pre-season, United could focus on other targets.
When asked about the chants of United fans last night, Kane refused to be drawn.
He said: “I’ve heard what they said, but I’m just focused on this team and trying to finish strong.”
Spurs’ all-time leading scorer then spoke about what happened to Spurs earlier this week when Cristian Stellini was sacked as interim head coach on Monday.
He said: “The chairman has asked for a meeting. I won’t go into what was said, obviously, but I think it was important [for him] to understand where the players’ heads were at the time.
“Obviously based on this result. And it wasn’t just this result. It had been building since the international break when we conceded both goals against Southampton.
“It was an honest conversation about where everyone is and what we need to try to do to give ourselves the best possible chance of finishing the season with something.
“We are still fighting for fourth place, but if it is not fourth, we will try to get as close as possible to fifth or sixth place.
“It’s so competitive in this league that you can easily end up 8th or 9th if you’re not careful. It was to give us the best chance. And I’m glad we reacted that way today.”
