Juventus coach Antonio Conte was delighted with how his side handled a hostile crowd.
"It was a difficult match and in this atmosphere with Celtic playing with the intensity they did we could have lost the match," he said.
"But my players kept their heads and showed great maturity and overall it was an excellent result for us."
PSG looked to be cruising as first-half goals from Argentinian duo Ezequiel Lavezzi and Javier Pastore gave them a comfortable lead until the mad last two minutes where Valencia's French centre-back Adil Rami scored and Ibrahimovic saw red.
PSG coach Carlo Ancelotti -- who will also be without the increasingly influential young Italian midfielder Marco Verratti for the second leg due to suspension -- was not happy with the sending-off decision.
"I don't understand the decision," said the Italian.
"He went for the ball at the same time as another player did. It was a forceful tackle but a football tackle. I really don't understand."
His Valencia counterpart Ernesto Valverde said his side had not been cautious enough and discounted the importance of the absence of Ibrahimovic in the second leg.
"They were very strong. Every counter-attack they had was very dangerous," he admitted.
"We managed to get a late goal, which means we still have a chance, but we must take into account the fact they have some extraordinary players." AFP SSC
