Tunisia fullback Oussama Haddadi has warned England and Belgium that they won't have it easy in Group D.

The African nation and Panama are overwhelmingly underdogs to progress through to the knockout stages of the World Cup.

But Haddadi, who plays at club level for Dijon, believes the Eagles are able to cause an upset.

"We had a good qualifying campaign," Haddadi told Goal. "It hasn't been easy but we're preparing well.

"We know that it won't be simple getting past the first round because we're in a difficult group with England and Belgium, but we'll do everything we can to cause a shock.

"We must not be afraid of other nations. We must be confident, play our game and show the true face of Tunisia."
