Bayer Leverkusen head coach Xabi Alonso reacted to the 0-3 defeat to Atalanta in the Europa League final two weeks after the game.
Xabi Alonso, Getty Images"At the moment it hurts. It is very painful. Such games should not be forgotten. But I feel that this will be more useful for my development as a coach than winning a treble," CNN Sports quoted Alonso as saying.
Last season, Bayer won the Bundesliga and the German Cup.
