Swedish coach Lars Lagerback has drummed into his players that losing focus against the Group B outsiders could prove costly in the final analysis.

Defender Olof Mellberg believes the group will develop into a three-horse race, with Trinidad & Tobago the also-rans.

"It's wide open and we are determined to make it hard for England," said the centrehalf.

"In South America, they will think Paraguay have a really good chance of going through and if you ask people in Sweden, they will back us."

Sweden won a tough group four years ago ahead of England, Argentina and Nigeria and hope to do it again.

They rattled in 30 goals in their 10 qualifying matches, their potent attack led by Henrik Larsson, Zlatan Ibrahimovic and Freddie Ljungberg.

They will have to field an inexperienced goalkeeper after first choice Andreas Isaksson suffered concussion when he was felled by a shot during a training session on Wednesday. The choice is between John Alvbage and Rami Shaaban.

PRAYER POWER

Trinidad & Tobago are the smallest country in the finals -- the two-island country has a population of just 1.1 million. Their defence will be led by the astonishing Marvin Andrews.

The devout Christian ignored medical advice to get an operation for a cruciate ligament knee injury, instead relying on the power of prayer to heal the problem.

"For me, Marvin is as safe as the Bank of England," said coach Leo Beenhakker. "He puts his heart and soul into games and can do it against the best strikers.

"We know our group is full of top attackers. Sweden have Henrik Larsson and Zlatan Ibrahimovic and they are an awesome pairing."

Beenhakker believes his players already know the side that will line up against Sweden on Saturday.

"They know who will start, I don't have to tell them, and they are not stupid," Beenhakker said.

The Dutchman is upbeat about the task his eclectic team of journeymen face as group minnows and believes they could just cause an upset.

"I think a lot of people will be surprised at what we will be able to do at the World Cup. This is a very good squad of players."
