New Delhi, Aug 24 - Harbhajan Singh believes the Sri Lanka tri-series will serve as a build-up to the upcoming Champions Trophy. The Indian cricketers will begin their long season with the tri-series in Colombo that involves New Zealand besides the hosts.

The Indians will then be heading for South Africa for the Champions Trophy that begins Sep 22.

The Indian off-spinner Monday said India will be the favourites to win the Sep 8-14 tri-series.

'We have done well against New Zealand in New Zealand recently. We have also performed well against Sri Lanka in the recent ODI series. In fact, we have beaten all the sides in the last two years. If we play to our potential, we will win the tournament,' Harbhajan said during the trophy unveiling ceremony of Compaq Cup here.

'The tri-series at Sri Lanka will be a good build-up for the season ahead with Champions Trophy starting immediately after that.'

'There is a good mix of youth and experience in the team.
