Tottenham Hotspur manager Andre Villas-Boas reveals his experiment with Gareth Bale at left back is unlikely to be repeated.

The Welsh winger linked up at left back after injury to Benoit Assou Ekotto ruled the Cameroonian out of Spurs' match against QPR.

But in a disappointing first 45 minutes Bale was ineffective, and QPR took a first half lead thanks to a Bobby Zamora goal.

Villas-Boas brought on Steven Caulker in the second period, switching Jan Vertonghen to left-back and pushing Bale further forward into his more familiar left midfield role.

And Spurs enjoyed a much more successful second half as a result, scoring two goals in the space of two minutes to turn the tie around, eventually holding on for a 2-1 victory.

The victory gave Villas-Boas his first win at White Hart Lane since becoming Tottenham boss, and the Portuguese manager admitted the half time change did the trick.

"We decided to play with Gareth at left-back because we thought he would give us more width," Villas-Boas told The Sun.

"But we were much more steady in the second half when we made changes."

Bale began his career as a left-back at Southampton, before moving to White Hart Lane while still a teenager.

But his performances further up the pitch convinced former-Spurs boss Harry Redknapp that the Welshman was best utilised in more advanced positions, with Bale even given license to play through the middle on occasion.
