Former Lazio captain Paolo di Canio admits there'll be relief after their Champions League win at Celtic.
Lazio won late on thanks to Pedro's effort.
Di Canio later said: "This time Lazio overturned Celtic after the opposite had happened in previous matches.
"It comes at a critical moment, it's a game won in a dirty way and it was needed. Two substitutes, Isaksen and Guendouzi, fought on the ball and it was he who decided who won the international tie.
"He crossed the ball with purpose (for Pedro), he knew it had to be perfect."
