WATFORD keeper Mart Poom admits he is a major doubt for Estonia's match with England at Wembley on Saturday.

Poom was ruled out of Watford's match at Scunthorpe on Saturday with an ongoing back problem and he is facing a race against time to be fit for the weekend.

"I have a back injury - prolapsed discs - so I'm really only 50-50 for the England qualifier," said Poom who signed for the Hornets from Arsenal in the summer.

"The manager's been very considerate and knows it's been my dream since I was a boy to play at Wembley.

"I've been playing the last few games just trying to get through them, but it's been getting worse and worse."
