Alexandre Lacazette’s hat-trick ensured Lyon avoided a French Cup upset by beating fifth-tier Chambery 3-0 to reach the round of 16.
Lyon are under pressure from their unhappy fans after poor recent performances and could ill afford to slip up at home.
Lacazette settled nerves with his first goal in the 11th minute and made it 2-0 in the 33rd, set up both times by Brazilian Tete.
The hat-trick was completed midway through the second half, taking Lacazette’s season tally to 14 in 21 games since joining Lyon from Arsenal.
There were no upsets on Saturday as Toulouse, Lorient, Reims and Angers were the other top-flight teams to go through.
Toulouse scored twice in four minutes as they beat Ajaccio 2-0 in an all-first division game. Zakaria Aboukhlal and Rafael Ratao netted midway through the second half.
Lorient won on penalty kicks at second-tier Bastia following a 1-1 draw, and Reims triumphed at fourth-tier Les Herbiers 3-0.
Angers scraped a 1-0 win at Olympique Strasbourg Koenigshofen, who have the longest name but were the smallest team left and playing in the Alsace regional league.
Top-flight neighbor Strasbourg allowed the minnow to borrow their stadium and nearly 20,000 fans attended. OSK normally have 100 fans watching their home games.
Angers are rock bottom of the first division and have not won a league game since September, so defender Miha Blazic’s 16th-minute goal was a relief.
