Slovenia midfielder Robert Koren says the result of Saturday's game against England is not important.
The 28-year-old West Brom star is set to line up against the Three Lions at Wembley, but admits his team will be focused on their midweek World Cup qualifier against Poland.
Slovenia, ranked 54th in the world, lie third in their qualifying group and can still qualify for the South Africa tournament if results go their way.
"We are not focused on playing England," Koren told the Sun.
"England are a big team and when they asked if we were ready to play against them we couldn't say no. But it's not a good time for us to do it."
Slovenia boss Matjaz Kek said: "Playing at Wembley will be great but my mind will be on Poland."
