Wales manager Chris Coleman believes Belgium have a real chance of winning the 2014 World Cup.
Coleman's side travel to Belgium on Tuesday for the final match in their World Cup qualifying campaign hoping to cause an upset after Marc Wilmots' team sealed their place in next year's tournament.

But the Welshman admits it will be tough to overcome a team featuring the likes of Eden Hazard, Romelu Lukaku and Marouane Fellaini, insisting every team should fear Belgium in Brazil.
"They were 40th in the world when we first played them in Cardiff at the start of the campaign. Now, they are sixth," Coleman said. "They are a very good team.
"We've been doing our homework on them and pound for pound and player for player, they have the most expensive squad in the world. I'd fancy them at the World Cup. They have a real outside chance.
"They are a very good team. It's a difficult test for us on Tuesday night. I don't think there will be many teams looking at them thinking, 'We'd like to play them'."
The in-form Aaron Ramsey led Wales to a 1-0 win over Macedonia on Friday and Coleman believes the Arsenal midfielder would not look out of place in the talented Belgium side.
"I'd put Aaron in any team because of the way he is playing," he added. "There's not a manager who wouldn't have him in his team every game.
"He could play in the Belgian team, absolutely, and I don't say that because I'm Welsh. He's that good."
