Russia coach, Fabio Capello, praised his team's resiliance after a 1-1 draw against South Korea in Group H on Tuesday.
After Lee Keun-ho's long-range effort slipped into Russia's goal to put the Koreans ahead in the 68th minute, Aleksandr Kerzhakov scored to pull Russia level just six minutes later.
"It was a good game, they ran a lot in the first half, but then they were tired," Capello told the BBC.
"The goal they scored, it was not easy. But the reaction from the players was really good.
"This is really important for me, the reaction, and we had chances to score the second goal.
"I know Kherzhakov very well, he is a fantastic player and he always gives us a chance to score goals."
Kerzhakov's equaliser was his 26th international goal for Russia, making him the join-record goalscorer for his country alongside Vladimir Beschastnykh.
Korea's was gifted its goal when Keun-ho's long shot slipped through the hands of Russia's keeper Igor Akinfeev, one of a series of mistakes for the CSKA Moscow goalstopper.
"Just like some players can miss penalties it can happen that a keeper makes a mistake as well," Capello added.
"You can accept a mistake from a great keeper like Akinfeev. Today it turned out fine."
