"I am sure Sourav will come back stronger after serving the ban and lead the team," Yuvraj said on the sidelines of a function organised by the Delhi Diabetes Research Centre.
Ganguly has been banned from six One-day Internationals by the International Cricket Council (ICC) after the team failed to maintain the desired over rate in the third and fourth ODIs against Pakistan earlier this month.
He would miss the first four ODIs of the triangular series in Sri Lanka due to the ban.Asked whether the absence of Ganguly was felt in the last two matches against Pakistan, Yuvraj replied in the affirmative.
"Yes it did affect. After all it is Sourav's team. He has led the team for last five years and made it in what it is today."
On his plans in the off season, the left-hander said he was interested in playing for some County in England but was quick to add that he was not having any immediate offers as of now.
Yuvraj, who interacted with children during the function, advised them to concentrate on fitness and asked their parents to maintain a healthy diet to keep them away from diseases like diabetes.
He also released a booklet giving information regarding diabetes, published by the centre.
