Gareth Bale tackled by Cristiano Ronaldo during Real Madrid training

World-record signing Gareth Bale is almost taken down by Cristiano Ronaldo during a Real Madrid training session, ahead of Bale's expected debut for the club.

Ronaldo appears to be apologetic after the challenge, which happened as the team prepared for their La Liga match against Villarreal on Saturday.

Bale moved to the Bernabeu from Tottenham for £85.3m earlier this month, a figure that meant he overtook Ronaldo - who cost Real £80m in 2009 - as the world's most expensive footballer.
