India hadn't won an ODI series of particular importance since their wins against Australia and West Indies in the 2013-14 home season. They had lost to South Africa and New Zealand away, and also did not have an impressive outing in the Asia Cup in Bangladesh either.
But the recently-concluded five-ODI series in England has been an easy affair for them, given the hosts' frailties in the ODI format, as India posted a comprehensive 3-1 win.
"You can only prepare a team by winning matches. And it is a good win if you consider that they did not win any ODIs in either South Africa or New Zealand.
"India are placed quite well for the World Cup. They have played some good cricket here in England in the ODIs. And as long as they keep playing good cricket and keep winning, they will find the right combination for the World Cup," he added.
"I thought there were good signs about India's bowling. Mohammad Shami bowled really well in this series.
"Bowling in the death-overs is something they will have to get better at and it is tough because almost every bowler gets hit in the death-overs nowadays. But let us not be too judgmental. India were outstanding with the ball in this series," said Ganguly, who led India to the final of the 2003 World Cup in South Africa.
