Borussia Dortmund coach Jurgen Klopp has praised his side's "mature" performance against Arsenal in the Champions League on Tuesday.

Robert Lewandowski's strike eight minutes from time proved to be the difference as the German side ran out 2-1 winners at the Emirates Stadium.

"Both teams battled hard against each other but we were always alert and ready to decide the game with one attack," UEFA.com quotes him as saying.

"After it happened, we did a great job [to hold on to the victory], especially in the last eight minutes. It was a great performance and we were very mature."

Dortmund, Arsenal and Napoli have collected six points each from their respective three matches in Group F.
