Bale's former Southampton teammate says England cannot view Wales as a one-man team.

Bale has ruffled plenty of feathers in the England camp during the build-up to this week's Group B contest, insisting Chris Coleman's men have a better team spirit than their rivals - comments that Three Lions' boss Roy Hodgson branded as disrespectful to his team.

The Real Madrid star was unsurprisingly at the heart of his team's opening win over Slovakia on Saturday, curling home a terrific freekick to inspire his side to a 2-1 victory.
He is widely expected to be the main man to watch once again in Lens, although former Southampton teammate Lallana insists it would be unwise for England to focus all of their energy on the former Spurs star.

He said: "You don't want to leave your team too vulnerable on the counter-attack with players like Gareth Bale playing, and the strengths and qualities that he has, but it's not a one-man show. They've got plenty of other good players.
"I have the pleasure of playing with Joe Allen and know what a talent he is. Aaron Ramsey is another one who is very talented, so we can't just put all our focus on Gareth, then get a sucker punch from one of their other good players.
"It's right we respect the whole team and look at their strengths and weaknesses, and figure out how we are going to beat them."
Lallana and Bale were once teammates at Southampton, but will face off in search of Euro 2016 glory on Thursday
Bale was mainly used as a left-back when the two players were at St Mary's, and Lallana admits that it has been interesting to watch him develop into one of the most exciting attacking players of his generation, adding that such a renaissance could be used as an inspiration for younger players.
"It's refreshing to see that someone can turn from a left-back into... I wouldn't even call him a winger because he plays up front now," he said. "I think for young players coming through, that's great to see and he's a real role model."
Bale will need to be at his best if Wales are to record a positive result, as his team have not beaten Thursday's opponents since 1984.
