Pep Guardiola’s men boasted 70 per cent of possession at Stamford Bridge, and took 25 shots at Chelsea’s goal, compared to the home side’s four.
The Spanish midfielder was speaking ahead of Tuesday’s return tie at Camp Nou and Iniesta is optimistic his side can overturn deficit and reach the final on May 19.
|12/5||Andres Iniesta is 12/5 with Bet365 to score at any time when Barcelona play Chelsea on Wednesday night.|
Iniesta told the Daily Mirror: “We were the superior team at Stamford Bridge.
"I don't think the luck will be with Chelsea in the second leg.
"I think if you judge the game on its merits, then we deserve to reach the final in Munich."
Barcelona lost 2-1 against bitter rivals Real Madrid at Camp Nou on Saturday to virtually surrender their Liga title. And Iniesta acknowledged that another setback at home would be hard to take for the reigning European champions.
"Defeat to Real Madrid followed by being knocked out by Chelsea would be a disaster, but we are optimistic," he said.
"If we score early, then I think we can go through. We have to make sure we do not concede.
"We know it won't be easy, but it's possible to reach the final."
