Aston Villa boss Unai Emery praised his players after their 2-1 win against Europa Conference League opponents AZ Alkmaar.
Villa came from behind to triumph thanks to goals from Diego Carlos and Ollie Watkins.
"The reaction after we conceded was fantastic," said Villa manager Emery.
"We have to be strong and take experiences like tonight to know how to win in Europe against really good teams.
"Very important, very difficult match. We knew we needed to respect them and try to play at Villa Park.
"They scored the first goal. We scored one that was offside more or less. I'm very proud of our work in this competition. We're getting better.
"AZ are a very good team. I'm very happy.
"We have to accept the referee's decision always.
"Legia are doing very well. We are excited to play the next game here."
