The Spain international was left delighted with the Blaugrana's display as they reached the quarter-finals of the Champions League
The Catalans recorded an impressive 4-0 win at Camp Nou to book their ticket for the quarter-finals of the Champions League after previously losing the first leg of the round of 16 tie 2-0 at San Siro, and Iniesta was delighted with Barca's comeback.
"To date it was one of the most complete games we’ve played. Hopefully this experience will help us in the future," Iniesta was quoted as saying on the club's official website.
"The team played brilliantly and we achieved our objective. When you have that kind of unity between the team and the fans games can be very long for our rivals at Camp Nou.
"We had an obligation to try and fight back and that’s what we did. The feelings we transmitted on the pitch were fantastic. When we show our identity, we’re very hard to beat. At times things do go the way you had hoped."
