Dortmund effort earns kudos from Klopp

Coach Juergen Klopp said Borussia Dortmund produced a near-perfect performance to leave it on the verge of the Champions League's quarterfinals after routing Zenit St. Petersburg in Russia on Tuesday.

Poland striker Robert Lewandowski scored twice as Dortmund romped to a 4-2 win at Petrovsky Stadium in the last-16 first-leg clash.

Klopp was delighted as Borussia bounced back from Saturday's shocking 3-0 loss at relegation-threatened Hamburg in the Bundesliga.
