England manager Fabio Capello has identified Gareth Bale as the main threat to his side at Wembley Stadium this evening.
A victory over Wales would all but guarantee the hosts' participation at the European Championships next summer, but Capello believes that Tottenham Hotspur winger Bale could prevent England from taking all three points.
"Bale always makes a difference. He is a really, really, important player for Wales," said the coach.
"We need to find a system to stop him and stop people passing to him.
"I have watched [Wales's] game against Montenegro and he played really well. He is a really good, important player."
A calf injury prevented Bale from playing when the two sides met at the Millennium Stadium in March, a match England won 2-0.
