English hope has been in superb shape this season with seven goals and six assists in 26 Premier League starts and has the keys to keeping his childhood club in the Premier League.
And, according to the MEN, United prefers to sign Grealish over Leicester City star James Maddison.
United should take a step forward for Grealish in the next transfer window, and reports suggest Ole Gunnar Solskjaer may be willing to spend up to £ 70 million to keep him away from Villa.

Grealish has also been linked to Manchester City, as well as the Spanish duo Barcelona and Real Madrid.
And, during a question and answer session on Instagram Thursday evening, Grealish admitted his ambition to play in Spain one day, while also suggesting that he would like to end his career in MLS.
When asked where he would like to play outside England in the future, the 24-year-old said: “Spain, but later in life (I would like to) play in the States -United. “
Grealish Villa teammate Conor Hourihane recently admitted that the playmaker was too good to play with Dean Smith’s team at the moment.
“He is top notch, first class. In terms of sheer ability and skill level and technique, he is easily the best player I have ever played with, “said Hourihane to the Southern Star podcast.
“He just received this gift. He runs faster with the ball, when he faces someone, you are really in trouble. He jumps so easily in front of the best players in this league. “
“He has grown over the three years I have been here – he has taken his game to a new level – especially this year in the Premier League.
“He really took it by storm. You know, the England team and taking that big step is only a matter of time because, if I am brutally honest, it is too good for our team at Aston Villa. “
