Up against the number one side in ODIs, South African coach Russell Domingo today said that facing India in the three-match one-day series starting here tomorrow will be a "tough assignment" for the Proteas.

"It's a big gauge for us. Look, we've won five of our last eight one-dayers, so we're heading in right direction, there is no doubt about it. But we know that India are going to be a tough assignment for us," Domingo said.

"They are coming off outstanding performances, albeit in India and under Indian conditions, but we are really looking forward to it. We need to see where we are going," the coach was quoted as saying in the South African media.

India are on a high having beaten Australia and the West Indies in their last two ODI series.

"India are a quality side and a big attraction, and we would have liked to test ourselves against them, but that's the way it is and there's nothing we can do about it," he said.

The South Africans' weakness against spin was exposed by off-spinner Saeed Ajmal in their last ODI series against Pakistan but Domingo thought otherwise.

"I don't think it's spin bowlers, I think it's one or two spin bowlers. Saeed Ajmal is the number-one ranked (ODI) bowler right now. He's a world-class spinner, he has been for a period of time, and particularly when you play him under conditions like we had in Dubai, Abu Dhabi, Cape Town and Port Elizabeth as well. He's always going to be tough.

"A lot of batters have struggled against him and a lot will still struggle against him. I don't think we've got a weakness against spin bowling, just that Saeed Ajmal is a world-class bowler and I'm glad he's back in Pakistan.
