Federico Gatti scored with a header seven minutes into added time to earn Juventus a 1-1 home draw against Sevilla in their Europa League semi-final first leg on Thursday.
Europa League kings Sevilla ignored the heavy rain and the pressure of the Italian crowd at a packed Allianz Stadium to dominate the game and looked well on course continue their bid for a record-extending seventh title before Gatti's last-gasp effort left the tie evenly poised.
Sevilla started strongly and Juve goalkeeper Wojciech Szczesny made a brilliant save to stop Youssef En-Nesyri's close-range header.
Lucas Ocampos missed a sitter for the visitors but Morocco striker En-Nesyri scored with a tidy finish from close range in the 26th minute after a quick counter-attack led by Ocampos.
Sevilla could have extended their lead before the break but En-Nesyri and Ocampos wasted good chances and Szczesny denied a thunderous strike from distance by Ivan Rakitic with a superb diving save.
Toothless Juventus recorded their first shot on target in the 65th minute when substitute Samuel Iling Junior tried his luck from distance with a tame strike that Sevilla goalkeeper Yassine Bounou easily held.
Juventus were energised by substitute Federico Chiesa, who is still working his way back from a long injury layoff, and equalised with the last play of the game.
Chiesa won a corner, Paul Pogba headed the ball into a crowded six-yard box and Gatti jumped high to head home the equaliser.
AS Roma grabbed a 1-0 home victory over Bayer Leverkusen in their Europa League semi-final first leg on Thursday thanks to 20-year-old Edoardo Bove's second-half goal.
Roma youth product Bove stabbed in the winner on the rebound in the 63rd minute for his first European goal.
Roma, bidding to win back-to-back European titles under coach Jose Mourinho following last season's Europa Conference League triumph, travel to Leverkusen next week for the return leg.

"I'm especially happy with the result," Bove said. "It was essential to win this first half and go there on Thursday with the same desire.
"Today we put great intensity into our game and we are happy. At first they made it difficult for us and it took us a while to adjust but then we controlled the game very well."
It had all started according to plan for Xabi Alonso's Leverkusen, who have not made a European final since their 2002 appearance in the Champions League showpiece.
In a lively start they came close twice, with Robert Andrich's shot saved after 40 seconds and Florian Wirtz wasting a golden chance when he fired wide.
The hosts, missing several players through injury and with Paulo Dybala and Georginio Wijnaldum not fully fit yet and on the bench, responded with Roger Ibanez's powerful header which Hradecky palmed wide with a superb reflex save.
They broke the deadlock just past the hour when Bove started a move and stabbed in on the rebound after Hradecky had saved Tammy Abraham's shot.
The visitors almost bagged an unexpected equaliser towards the end of a scrappy second half but Jeremie Frimpong's 87th-minute shot was blocked on the line.
