Wayne Rooney warns against overconfidence but predicts England will qualify for World Cup finals They are going to be two tough games, though, because Montenegro and Poland are good sides and their best qualities are on the counter-attack. England will have to be patient in both games and will need an expectant home crowd to remain supportive, even if they are struggling to break down the visiting defence. The last thing England's players should do, as they did when falling behind against Germany in the 2010 World Cup and against Croatia when they lost at Wembley and failed to qualify for the European Championships in 2008, is panic if things do not run smoothly early on. "We've got some great young players emerging this season, as we've seen with Daniel Sturridge, whose scored again today and Danny Welbeck," added Rooney. I'm confident, we're confident, but you always have to be sure you're not overconfident.
