Mumbai Indians have lost half of the eight matches they have played. Chargers have not fared well either, losing five matches out of eight contest so far.
Sangakkara said may be its time to take advantage of Mumbai's poor form but remained cautious.
"Probably, but we know how good a side Mumbai is. We beat Pune and hope to keep the momentum going. In T20, it is just about playing the best cricket on the day," said the former Sri Lanka skipper ahead of their match at the Wankhede Stadium tomorrow.
Sangakkara also hoped his team would be more disciplined when confronted with a close game again in tomorrow's match after losing the first leg at Vishakapatnam in the last over.
"We came close to beating Mumbai in our first game which we probably should have won. They needed 18 in the last over and Rohit (Sharma) was brilliant in that over. If we get them into such positions, we have to be tighter and bit more disciplined to win the game," said the 34-year-old Sri Lankan, who has played 108 Tests and 325 ODIs for the Emerald Islanders.
Sangakkara said his team, which is languishing at the bottom of the nine-team IPL table with only three points ahead of their eighth encounter, should have won three more games at least but rued the lost chances.
"I think we played very good cricket so far, but lost out on crucial moments of the game. It may be a little error on the field or falling 10 runs short. We had four winning opportunities, three of which we should have closed out
