David Luiz says 'ambition' was the reason he decided to join Arsenal this summer and insists staying at Chelsea would have been the easier option for him.
The curly hair defender left Chelsea to join fellow London rivals for a reported £8 million fee on a two-year deal.
The 32-year-old over the weekend made his Gunners debut in their 2-1 over Burnley as he formed a partnership with Greek international Sokratis Papastathopoulos at the heart of defence.
