Berbatov, signed from Tottenham in a £30 million deal three years ago, has made just one start in the Premier League this season.
The 30-year-old is now in the final year of his contract - although United have a unilateral option to extend by further year - and has recently been linked with Paris St Germain and Galatasaray, but the situation has not affected his relationship with Ferguson.
Berbatov told MUTV: "The way he treats players is unbelievable. Even when not playing or you're injured, he's still speaking with you and encouraging. He makes you feel special and lets you know your place in the team."
Berbatov feels it is up to him to impress in training and win his place back in the side. "Some players need to be pushed and others need to be talked to separately," he said.
"For me, he just needs to come to me and tell me what to expect from the game and the training ground, then it is up to me to show I can play every game.
"I cannot speak for other players, but it is always good when the manager comes to ask how you're feeling and makes you feel calm before you play the game.
"For me, he knows how to motivate you and how to speak with you, about football or some issues you have outside of football. Just in the way he speaks with you in the team-talk - before important games he can make you feel like it's the last game you'll play in your life, so you go out there and want to give everything you have.
"It's great - you just need to be there to see it."
He added: "Even when we're on the training ground or go to lunch, for example, it's like he is one of the team - joking around and telling stories, asking quiz questions.
"He really likes the quiz questions and it's good because he relates with the players and he's really good like that."
Ferguson celebrated 25 years in charge at Old Trafford last weekend and Berbatov has been impressed by the way the Scot has continually renewed his side.
Berbatov said: "Every time a player retires or goes to another club, he always a back-up plan on how to replace the player and build the team again."
