The £32 million-rated Belgium international has already announced that he will leave Lille this summer and once again confirmed that he will sign for one of the Manchester clubs in an interview on Monday.
Hazard says he has “90 per cent” decided on his future and newly-crowned Premier League champions City believe they are in line to land the 21-year-old barring a last-minute change of heart.
Both United and City are in constant negotiations with the player’s agent as he looks to secure the best possible deal for his client, who was voted the Ligue 1 player of the season and is one of the most highly rated talents in Europe.
Hazard will play his final game for Lille against Nancy on Sunday night and will confirm his decision on his next club the following day.
City have offered Hazard wages in the region of £100,000-a-week and the assurance of regular football to lure him to the Etihad Stadium. In an attempt to convince the attacking midfielder to join Roberto Mancini’s team, they have also shown him around the city to look at houses and he was a guest at the Manchester derby at the end of April.
Le Parisien has also suggested that City have agreed to play Lille in a pre-season friendly this summer to open the French club’s new stadium, which has prompted claims it could be part of a deal for Hazard.
Hazard has been in stunning form this season, scoring 17 goals and providing 15 assists at the club where he has spent his entire professional career after joining at the age of 14.
He has consistently spoken of his desire to play in the Premier League next term and when asked on Monday where he will be playing, he replied: "To Manchester, as I have already said. The decision will be taken soon.
"I have made my choice 90 per cent. There are always small things that can change everything. You will soon know where my future lies.
"City have won the title this year, and they have great players, a great coach and a nice project.
"At United, we all know [Sir Alex] Ferguson and all the talented players he has in his squad."
