Arsenal handed warning over Bale's firepower ahead of Spurs clash
Villas-Boas says Tottenham star can blast past Arsenal and confirm his credentials as one of world's best players alongside Ronaldo and Messi

Spurs boss Andre Villas-Boas has warned Arsenal that Gareth Bale will use today's crucial north London derby to prove he deserves to be ranked as one of the world's top three players.
Bale will be in the spotlight when Arsenal arrive at White Hart Lane for a potentially decisive moment in the battle to qualify for the Champions League.
Tottenham are in third place, four points clear of Arsenal in fifth, and a victory over their bitter rivals would be a blow to the Gunners' hopes of finishing in the Premier League's top four.
Tottenham will need another dominant display from Bale, who underlined his remarkable talent by inspiring Spurs to a 3-2 win at West Ham on Monday.
Bale scored twice at Upton Park, including a last-minute winner, to take his goal tally to 23 for club and country this season.
The 23-year-old's superb form has led to claims the Wales winger is now as influential as Real Madrid's Cristiano Ronaldo and Barcelona playmaker Lionel Messi. Villas-Boas has no doubts about Bale's brilliance.
