Terry said: "We had to be very patient, I don't think we touched the ball for the first 15 minutes but from Didi on his own up front, the midfield and defence, it was a great team performance.
"Didi is all about these big nights, the big occasions. He put fear into the Spurs defence at the weekend and he did that again tonight.
"He was up there on his own against some of best defenders in world and he did it brilliantly."
The second leg takes place at the Nou Camp on Tuesday next week.
