Rudi Garcia proudly announced Lyon "won the tactical battle" against Pep Guardiola's Manchester City in their shock UEFA Champions League win.
Lyon reached the semi-finals with a 3-1 success in Lisbon on Sunday (AEST) as City were dumped out at the quarter-final stage for the third season running.
Maxwel Cornet scored midway through the first half and Lyon rallied again following Kevin De Bruyne's equaliser, with substitute Moussa Dembele on target twice.
Lyon lined up with a 3-5-2 formation, which City matched, but Garcia's side looked far more comfortable than their opponents.
The coach explained to RMC Sport: "You have to expect everything with Guardiola, but we won the tactical battle.
"We have mastered our formation well. We have returned to a hybrid set-up to stop De Bruyne."
Tactics were not the only route to victory, though, with Garcia hailing Lyon's team spirit as they battled hard against seemingly superior opposition.
"I'm proud of my troops," he said. "We believed in ourselves. We knew we were not favourites against a big team, but we managed to qualify by scoring three goals and conceding only one.
"It is linked to our collective spirit. We saw everyone working to a high level for each other."
Garcia was also pleased for Dembele, who started from the bench but made a decisive impact.
"It was a disappointment for Dembele not to start, but I told him that he would be very important," Garcia revealed.
