David Beckham [Images] warned on Tuesday that his former Manchester United [Images] teammate Dwight Yorke will provide the World Cup threat when they face Trinidad & Tobago.

The two men were together at Old Trafford from 1998 to 2002, famously being a part of the Treble-winning season in 1999 when United won the European Cup.

Though Yorke, now 34, has left English football for Sydney FC in Australia and plays a deeper role for the Soca Warriors behind the strikers, Beckham senses danger ahead in Thursday's Group B game.

"Yorkie's always been a threat to any defenders and any team he comes up against," Beckham told a news conference on Tuesday.

"He's a great lad, but also he's one of the best strikers around and has been for may years.

"The time I spent with him at United was amazing -- we won the European Cup, we won leagues, FA Cups and he was a huge part of that team. It'll be nice to see him."

While England [Images] beat Paraguay 1-0, Trinidad & Tobago earned a 0-0 draw against much-fancied Sweden on Saturday despite being reduced to 10 men.

Beckham made it clear England will be taking nothing for granted in Nuremberg but were determined to get a win which would book them into the second round.

"Trinidad & Tobago, physically, are going to be ready. The result they got against Sweden might have surprised a lot of people but it didn't really surprise me.

"There will be a lot of respect on both sides but at the end of the day you're going to have to win a football match and you have to upset a few people by doing that.

"Yorkie's a great lad, he likes a laugh and a joke," said the Real Madrid [Images] midfielder. "But when he's on a football pitch he's a serious person and a player we have to be aware of."
