Vidic believes the change is the reason for the Bulgarian striker’s improved form.
Berbatov scored an hat-trick in United’s 3-2 victory over arch-rivals Liverpool on Sunday.
“We are all aware how good Dimitar is,” said Vidic. “His skills with the ball are incredible.
“The criticism he got last year was because he didn’t score many goals.
“This season he is scoring a lot, and important goals too.”
Vidic added: “He has learned what he has to do. He has changed his game compared to last season. He is in the box more and is more of a threat.
“Dimitar has always had a great touch and gave us composure, but because he is also going into the box, he is scoring goals.
“That is why he is getting so much credit.
“If he keeps doing that we have a good chance to win the league and for him to gain some personal reward by becoming player of the year.”
