AZ Alkmaar midfielder cannot hide his disappointment after BATE defeated his side 4-1 in their Europa League clash.
Elm believes the Dutch team were "not aggressive enough", and is speechless in trying to describe and justify the club's performance.
"BATE won just about every perosnal duel. We were always one step behind them and overwhelmed," Elm told the club's official website after the match. "Two years ago, BATE were playing in the Champions League, so we knew they would not give up.
"They have a lot of quality, and after they scored the first goal, we were unable to overcome this.
"This is a good lesson for everyone who played. We thought we knew what to expect, but were still surprised. During the next European away game, we will know what lies ahead. We learned a lot today," he concluded.
