Ritchie is a committed Berbatov supporter and he believes a run for Dimitar could be the key.
"I have always been a Berba fan. You will never have heard criticism of him from me," he told the Manchester Evening News.
"You never know what the manager has up his sleeve regarding selection and that's how it should be. But from Dimitar's perspective it would be great for him to get a few matches unbroken under his belt. There is no doubt that has to be a factor.
"You need consistency in your game and to help get that you want to be playing match after match. To have breaks thrown in, they must have a big bearing. At the moment you cannot see him not playing and, for his sake, I hope that continues.
"He is a class act and brings the Cantona-esque factor to United's game that I don't think we have had for a while - possibly since Eric's era. He holds the ball up so well, sees a pass and links play. For me it is also reminiscent of Jimmy Greenhoff at Old Trafford.
"In my young days at the club Jimmy and Stuart Pearson were up front and I tried to get both of their styles in my games. I particularly looked up to Jimmy. His control was superb, he too could pick a pass out and he scored goals as well. I think Dimitar is very similar."
