Slovenia coach Matjaz Kek believes his team could not have wished for a much tougher draw in the first round of the World Cup.
Kek, whose team beat Russia in the play-offs to qualify for the finals, will face England, Algeria and USA in Group C.
England are strong favourites to progress to the last 16 and Kek is also expecting a difficult challenge against the other two countries in the group.
"As far as I am concerned this is one of the toughest draws we could have had," said Kek.
"England are very strong opponents and the other teams will not be easy either."
Slovenia open their campaign against Algeria on Sunday 13th June and striker Milivoje Novakovic believes this will be a decisive game for his national team.
Novakovic told TV Slovenia: "We got a good group. The first match will be the most important and will determine our future.
"These are opponents we can beat. England is a favourite, but it is positive we play them last and that our fate will be determined before that."
Slovenia played England in a friendly at Wembley back in September when Zlatan Ljubijankic scored a late consolation in a 2-1 defeat.
