Brisbane:Kumar Sangakkara has rated the series win over Australia as the best of his captaincy, but said his team must avoid lapses like the one at the Gabba if it is to be the best in the world.
Sri Lanka followed their Twenty20 victory last week with two wins to claim the ODI trophy, but stumbled to an eight-wicket defeat in Sunday's dead rubber.
After their batting was so strong over the rest of the tour, the tourists were knocked over for 115 in only 32 overs to end their chances of a clean sweep.
"The real thing about today is we know we're a good team, but if we want to be the best, things like this can't really happen," Sangakkara said. "We are on our way to where we want to go, but we've got fine-tuning to do."
Sangakkara, who took over from Mahela Jayawardene in 2009, led the side to their first series victory in Australia and said the result was "definitely" the best result of his captaincy.
"We had a couple of targets, one was to try and beat India in India, which we couldn't do, and the other was to try to beat Australia in Australia. We managed to do that and it's a great team effort and we are very happy."
Sri Lanka now return home to prepare for a three-Test series against West Indies starting on November 15.
"Sometimes it's a good thing [not having much time between games], when you're in form and in rhythm," Sangakkara said. "Sometimes it's important to keep playing, and winning games."
