Coach Paulo Fonseca watched from the stands and saw his substitutions pay off as Lyon won 2-0 at Nice to maintain its push for a Champions League spot.
Fonseca began his nine-month touchline ban in Ligue 1 after aggressively confronting referee Benot Millot last Sunday. He saw his team struggle in the first half as Nice striker Gatan Laborde hit the post in the driving rain.
On Sunday, Lyon punished Nice when midfielder Rayan Cherki scored one minute after coming on. He latched onto a pass from Brazilian midfielder Thiago Almada and finished confidently in the 78th minute.
The 21-year-old Cherki has been linked with a move to a big club since breaking onto the scene as a precocious teenager five years ago, and this was his career-high sixth league goal.
The lively Almada then found Ghana forward Ernest Nuamah with a first-time pass and Nuamah who came on midway through the second half expertly curled the ball into the top left corner in the 83rd.
Sixth-placed Lyon is two points
