Jamie Carragher slammed a 'naive' Mikel Arteta for the way he set up his Arsenal side in their 2-0 home defeat to a Romelu Lukaku-inspired Chelsea side on Sunday.
Belgian striker Lukaku starred for the Blues in the London derby win at the Emirates Stadium, scoring once before Reece James struck before half-time to continue Thomas Tuchel's 100 per cent start to the Premier League season.
Arteta's Arsenal, meanwhile, have back-to-back defeats to begin their own campaign and Carragher claims the Gunners boss did not do enough to protect defender Pablo Mari from the threat of Lukaku.
