bat also bowled and fielded well when he struck form with the willow.
"Yuvraj is a very talented player. When he gets going he is one of the toughest batsmen to bowl to. He scores in every part of the ground. He is one of the players, when he gets going, he takes you through the series. You always believe that kind of player," Dhoni said.
He added that when the Punjab batsman gets going his overall form also hits a golden patch.
"When he bats well, his overall cricket goes up. Not only just his batting, his bowling and fielding too goes up. It has been good to see him score loads of runs," he added.
The captain also said the youngsters need to apply themselves and enjoy cricket without being desperate to be successful at this stage.
"They need to go out there and look to enjoy cricket. If they are too desperate then the chances of them being successful goes down. You should be relaxed, calm and cool.
"You have nothing really to prove. At times, I personally feel when you want to perform and do things you end up putting pressure on yourself. So it's better to be in a positive frame of mind," he said.
Looking back at the year, Dhoni said they have been performing as a team which was their recipe for success.
"We have individual performers who have done splendidly but as a unit we have done well. When spinners are not in form there were fast bowlers taking wickets and complementing each other. At the same time, batsmen are doing their job. Even the lower order is contributing," Dhoni said.
"It's the execution of the plans which is helping. Spinners, seamers, even part-timers are doing well," he added.
Asked whether he was aiming for a clean sweep which will help the side take the second spot in ICC ODI rankings, Dhoni said, "We are not looking whether to win the series 7-0 or have a 5-2 result. We are not thinking much on that."
Indirectly taking a dig at the ICC-approved Duckworth and Lewis method to decide a rain-affected match, Dhoni said, "Frankly speaking I don't understand Duckworth-Lewis. I just wait for the umpire's decision."
