Ganguly, who retired from international cricket recently, feels the "tough time" is only a minor part in Dravid's long and illustrious career, which has seen him write a number of success stories.
"I'm sure Rahul Dravid will sort his game out. When you perform for 13-14 years, it just doesn't go away overnight," Ganguly, who has accumulated more than 7000 runs from 113 Tests, told a news channel.
"Everybody must realise, the selectors, the board and the fans that when you play for so long you will have tough times. You will all have bad series because you are human. I back him to do well and get runs against England," he added.
Asked whether he wants to sit on the selectors' chair, the 36-year-old cricketer retorted saying, "I think the days of criticism are over for me. I have been criticised a lot as a player. I don't want to start all that again as a selector."
Ganguly, though, is yet to decide how to spend time post-retirement. "I haven't decided on anything. I need some time off. I need a break from the game, a break from everything... I'm trying to build a school, so I will give time to that. I want to do that in a big way so that I can help young boys and girls shape their careers," he said.
Ganguly, India's most successful captain, wants to contribute to the upliftment of Bengal cricket and guide budding youngsters in home town Kolkata.
"I will definitely do a little bit of work related to cricket. It could be media, it could be commentary. But I want to contribute to Bengal cricket," he said. "There is enough talent and hopefully I can guide them. Coaching is not an option now, not in another five years because it involves travelling," Ganguly said.
