Brighton striker Joao Pedro admits they need to learn fast after defeat to AEK in their opening Europa League game.
Pedro struck twice, but it wasn't enough as AEK won 3-2 at Falmer stadium.
The Brazilian later said: "Difficult to say mostly because it's the first time Brighton have been in the Europa League and today we conceded a goal too early. We have to see what we can improve and be ready for the next game.
"We know they're strong in corners and in attack. If you mark more active you do not concede these goals.
"If we had won this game it would be better but I'm happy to score today. I tried to help the team and we need to improve for the next game.
"We lost against West Ham as well and they play similar to them, we need to learn from today."
