The Germany international feels the title holders must step up their game in next week's return if they are to progress
Bayern enjoyed the majority of possession, but failed to create many clear-cut chances and even fell 1-0 behind when Nemanja Vidic found the net after the break.
Bastian Schweinsteiger restored parity shortly after to help the Bavarians to a draw, but Boateng has insisted they must do better in the return if they are to reach the semi-finals.
"We know they have quality players, but I think over the whole game we must be a bit disappointed because we had so much of the ball and didn't create so many chances," Boateng told Uefa's official website.
"We must move the ball quicker and create more chances; then I think we can get a good result at home. I am still confident.
"In the end it is a good result as we finished with 10 men but over the whole game we had a lot of the ball but didn't create too many chances and paid for it at a corner.
"We deserved a draw although they played well on the counterattack. I think at home we have a big chance of going through to the next round."
The return at the Allianz Arena is scheduled to take place on April 9.
