Marco Reus has claimed that Borussia Dortmund manager Jurgen Klopp got the tactics spot on as the German side beat Zenit St Petersburg 4-2 on Tuesday evening.

Despite scoring four crucial away goals in Russia, Reus believes that Dortmund still cannot afford to become complacent ahead of the second leg of their Champions League last-16 tie.

"We started very well. Our tactics worked perfectly, we took an early 2-0 lead and put in a fine display, especially in the first half," the German told UEFA's official website.

"In the second period we slacked off a bit and this should serve as a lesson to us for the return leg. Our 2-0 advantage was deserved, as was the final result, I think.

"I always say it doesn't matter what the individual does, but to win as a team, and that's what we have shown today."

The second leg takes place on March 19 at the Westfalenstadion.
