"Yeah, it has to be (one of the best). And I am pretty happy about it and am all the more so as we won the match and we kept ourselves alive in the tournament," Sangakkara said yesterday after the seven-wicket win that kept the Lankans in the tournament.
He also gave credit to Mahela Jayawardene and Nuwan Kulasekara for his side's win.
"We had to play well at the start, see off Jimmy Anderson but Mahela played really well and we got on top of it. Kulasekara took the pressure off me and those two big overs, off Graeme Swann and Stuart Broad, were decisive," said Sangakkara.
"That's the Champions Trophy for you, the pressure is on, players aspire to play in it. I'm pleased to have done well today. We've got to win another one, the Aussies are a tough outfit so we'll have to prepare well."
Captain Angelo Mathews was all praise for Sangakkara for his match-winning knock.
"We needed this win, to be honest. We started confidently and the bowlers were really good in the middle overs, we just had one go for 20 runs near the end," he said.
