Monaco showed little room for sentiment as they beat Borussia Dortmund 3-2 in a thrilling Champions League quarter-final first leg.
The Ligue 1 leaders gained the advantage thanks to Kylian Mbappe's double and a Sven Bender own goal.
And, after wearing T-shirts supporting their stricken team-mate in the warm-up, their first-half performance proved doubters right as Monaco, who also missed a first-half spot-kick, surged into a two-goal lead.
The second half was a different story and Ousmane Dembele and Shinji Kagawa goals either side of Mbappe's second left it all to play for ahead of the return leg in the Principality.
Dortmund head coach Thomas Tuchel criticised UEFA's decision to make his side play the game. "We were informed by text message that UEFA was making this decision," he said. "A decision made in Switzerland that concerns us directly. We will not forget it, it is a very bad feeling.
"A few minutes after this attack, the only question that was asked was, 'Are you ready to play?'. As if we had thrown a beer on our coach.
"At that time, we did not know the reasons for this attack. There is a feeling of helplessness. The date was imposed on us."
