Serie A champions-elect Juventus remained on course for the Europa League title with a 1-0 win at Lyon in a forgettable quarter-final first leg on Thursday.
After losing their 14-match unbeaten run in a 2-0 loss at Napoli at the weekend, Juve continued to labour in France.
They were heading for a scoreless draw until Leonardo Bonucci broke the deadlock five minutes from time.
Andrea Pirlo’s corner fell to Paul Pogba whose powerful close-range drive was blocked but Bonucci was on hand to blast the ball home past Anthony Lopes in the Lyon goal.
“It was tough as Lyon were trying to stop us from playing with man-marking all over the field,” said Juventus coach Antonio Conte.
“I think the victory is a deserved result, but we know that we have achieved nothing yet, there is a second leg to play and a semi-final to achieve.”
Portuguese giants Benfica and Porto both came out of their first legs with 1-0 wins.
Last season’s runners-up Benfica, who put out Tottenham in the last-16, won at Alkmaar in the Netherlands thanks to a 48th-minute goal from Eduardo Salvio.
He was first to a rebound after Alkmaar’s Costa Rican goalkeeper Esteban had saved from Oscar Cardozo.
Porto, the 2011 champions, edged Sevilla 1-0 with stand-in captain Eliaquim Mangala scoring on the half-hour.
Steven Defour and Ricardo Quaresma both saw efforts come off the post for Porto but they ended the game with 10-men after Fernando was red-carded.
Argentine playmaker Matias Delgado scored twice in the space of four first-half minutes to help Basel on the way to a 3-0 win over Valencia.
