The Red Devils have been linked with the talented German star and are said to be leading the race for the £60million-rated forward.
And though he does not want him to leave, Leverkusen assistant manager Marcel Daum thinks he has the potential to be just as good as Zidane – one of the best footballers of all time.
He said: “For me, he has the elegance of Zidane.
“If you see his movement, he’s very elegant, he’s always calm, he has great passing ability.
“What a lot of people don’t see, because we watch him every day, is that he’s pretty fast. That’s a big bonus.
“He’s a great player, he’s scoring goals, he’s great in the air and he’s pretty fast. It’s up to him how far he can go.
“I can’t say he will be the best German player ever, but he has the talent and there are no limits. He’s displaying signs of Zidane.”
Ole Gunnar Solskjaer is already working on a swoop for England attacker Jadon Sancho, who bagged his first ever hat-trick as he returned to Borussia Dortmund‘s starting line-up in a 6-1 Bundesliga rout of Paderborn.
United want to proceed in the summer as they know Havertz’s value will only increase.
They are expected to start with a £50million offer but may need to go further to get their man.
Havertz has caught the eye with his goals for Leverkusen this season — he has 15 strikes in all competitions.
But United believe he can play wide in a front three as well as through the middle.
United see former Manchester City youth player Sancho, 20, playing down the right, so Havertz would probably be on the left — with Marcus Rashford through the middle.
