Barca boss Pep Guardiola complained about German ref Stark's performance, claiming his players were booked unfairly.
Terry disagreed and praised the officials for being strong in a hostile atmosphere.
He said: "No I don't think it was a penalty. It's an intimidating place for players and referees to come."
But Terry is backing the Drog to do the business in the second match.
The skipper added: "I thought Didier was unlucky. We didn't create too many chances but we haven't conceded.
"The form he's in, I'm sure he can do some damage to them when we get back to the Bridge next week."
