Despite boasting a numerical advantage for the entirety of the second-half following Aaron Cresswell’s controversial red card, Lyon fell a goal behind after some lax defending allowed Jarrod Bowen’s shot to deflect off of Jerome Boateng and over a scrambling Lopes.
Tottenham loanee Tanguy Ndombele did manage to level the scores but, for a team who were playing in the latter stages of the Champions League relatively recently, not being able to inflict further damage was undoubtedly disappointing.
Domestically, Lyon’s home form has tailed off in recent weeks.
While Peter Bosz’s side have won 8 of their 15 games at the Groupama Stadium, they have conceded seven times in their last three fixtures.
Certainly a team West Ham can exploit, no one in the top half of Ligue 1 have conceded more often at home this season.
Speaking after the game, goalkeeper Lopes said: “There are regrets about the way the game went.
“We went in at 0-0 at half-time. They got that red, but it’s a fight when you come to England and we had to stay alert. But we started the second half badly, we conceded a goal that I think was a bit unprofessional. We reacted well afterwards, even if I think we could have come away with a more positive result.”
