The Ligue 1 leaders squandered a 2-0 aggregate lead with just half an hour of the tie remaining, losing 3-1 in the second leg and 3-2 on aggregate thanks to Karim Benzema's hat-trick.
It means head coach Mauricio Pochettino could already be looking ahead to a change of scenery.
TOP STORY – POCHETTINO SET FOR PSG SACK AND COULD TURN TO MAN UTD
Mauricio Pochettino's job is "hanging by a thread" at PSG, according to the Telegraph.
It is claimed the Argentine can expect to leave the club at the end of the season following their Champions League collapse against Real Madrid.
Pochettino has long been linked with the Manchester United manager job and could now start to prepare for the prospect of taking over at Old Trafford.
ROUND-UP
- Cristiano Ronaldo has spoken with agent Jorge Mendes over his future at Manchester United, claims the Sun. Meanwhile, Bild reports the Red Devils are interested in signing Robert Lewandowski.
- Paul Pogba is another who could be leaving Old Trafford this year, but Juventus are not yet certain whether to try to re-sign him on a free transfer or offer a new contract to Paulo Dybala, Tuttosport claims.
- Barcelona are close to concluding an agreement with Chelsea defender Andreas Christensen, according to Sport.
- Arsenal want to sign two new strikers and a midfielder as part of a major squad overhaul, the Standard says. Alexander Isak, Dominic Calvert-Lewin, Jonathan David and Darwin Nunez are among the forwards being tracked.
- A consortium led by British businessman Nick Candy is working on a £2.5billion bid to buy Chelsea from Roman Abramovich, the Guardian reports.
Barcelona captain Lionel Messi moved one ahead of Ronaldo for the Ballon d'Or record, claiming his sixth individual honour in December.
The result came despite Ronaldo helping Juve to an eighth consecutive Serie A title and Portugal win the inaugural Nations League crown.
Sari is determined for Ronaldo – who sat out Wednesday's 4-0 Coppa Italia last-16 victory over Udinese through illness – to add to his Ballon d'Or collection and match Messi.
"I would like to help Cristiano win the sixth Ballon d'Or first," Sarri told reporters post-game in Turin.
"It's really annoying thinking that someone won more [Ballons d'Or] than him. I think about him and I think helping him it is my goal and the goal of the team. It is right for him.
"[Paulo] Dybala is going to be one of the contenders in the next years. I think so."
While Ronaldo sat out, Juve forward Paulo Dybala dazzled with a brace and an assist against Udinese.
Dybala teed up Gonzalo Higuain for the 16th-minute opener following a stunning piece of combination play before curling a memorable strike past Nicolas approaching the hour mark, having converted a first-half penalty.
It took his season tally to 11 goals across all competitions and Sarri added: "Dybala is a top player. As every top player when they are becoming confident and having the right age, they are playing like a top player.
"I don't think a manager can teach something to a top player. Dybala is going to leave a mark in world and European football in the next years. He has got the right age to leave a mark and he's still got many years of his career. He is really confident in this moment after a few difficulties in the past."
Sassuolo were much the better side in the first half of the Serie A clash at MAPEI Stadium – Citta del Tricolore on Monday and they were rewarded when Giacomo Raspadori put them in front.
Paulo Dybala equalised on the stroke of half-time, though, and substitute Kean's first goal for two months in the 88th minute snatched a huge win for the Bianconeri.
Juve remain in fourth place with four games to play, eight points better off than Roma in fifth spot and just one behind Napoli.
