Arsenal manager Arsene Wenger believes defeat for either France or England in next week's Group D clash could spell the end of their Euro 2012 hopes.
"The opening game is England v France and there is no Rooney. You would say that is a game that you can not afford to lose," Wenger said.
"Why? Not because you cannot catch up, but (because) the pressure inside the country becomes tremendous straight away.
"That game could dictate the whole group. If it's a 0-0 draw, the group is all open, but if someone loses they have a very good chance of going out because Ukraine will beat one of the two, you would say, and Sweden are a hard team to beat."
