West Ham United and Lyon played out a 1-1 draw in their Champions League quarter-final first leg at London Stadium.
But it was Lyon who took the dominant position, pushing the hosts deep inside their own half for most of the game.
Tottenham loanee Tanguy Ndombele eventually equalised after 66 minutes, tapping in from close range after a shot had been deflected into his path.
The second leg will be played in France next Thursday.
Speaking after the game, Hammers boss David Moyes was clearly unhappy with the referee.
"Firstly, you need to look at the foul on Jarrod Bowen in the build-up [to the red card]. I hoped VAR would look at that as it is in the same phase of play. I'm certainly not going to comment about the referee. I will answer other questions but I am not going to bother with the referee tonight.
"We were really resilient in the second-half. We came in at the break knowing with 10 men it was a difficult job. We stuck at it and had one or two opportunities ourselves. Overall it was more of a backs-to-the-wall performance second-half but we are still in with a good shout.
"I don't know if the pressure is off because we want to qualify. Generally the players stuck at it tonight. We didn't play well and we can only play much better next week."
