Spartak Moscow midfielder Demy de Zeeuw is urging his teammates to put their midweek defeat to Celtic out of their minds for Sunday's derby against CSKA Moscow.
The Dutchman was scathing of his team's Champions League performance on Wednesday, when Celtic forward Georgios Samaras headed a dramatic last-second winner to make it 3-2 after Spartak were reduced to 10 men.
"Against Celtic we didn't get the result we needed, and it put everyone in a foul mood," the 29-year-old said. "We have to forget about it and fight at all costs, we have to get the win any way we can."
Spartak, last year's runners-up to Zenit St. Petersburg, are fourth points off Anzhi Makhachkala's lead in the Russian Premier League, in fifth position.
Victory over second-placed CSKA would propel them into second, if results elsewhere go the way of Unai Emery's team.
CSKA look to bounce back from last week's shock 2-0 defeat to Dynamo Moscow, which ended a run of six-straight wins.
"The fans need to see us fight for every ball, and if we do it well for the full 90 minutes, we can get a good result," de Zeeuw said.
The former Ajax and AZ Almkaar player said he relished the opportunity to play Sunday at "one of Europe's most important derbies."
"A sold-out Luzhniki stadium, the crazy support of the fans, it's something incredible," he said. "On my first day in Moscow I saw photos of the derby in a club office. I was massively impressed and happy that in my football career I've had the honor of taking part in games like that."
De Zeeuw moved from Ajax in July 2011, and has two goals in 20 league appearances for Spartak.
