Chelsea remained unbeaten under new coach Guus Hiddink after conceding a late equalizer to draw 2-2 at home to West Bromwich Albion in the Premier League on Wednesday.
Unmissable with a protective black mask, Cesar Azpilicueta put Chelsea ahead after 20 minutes, turning in a low cross from Branislav Ivanovic.
West Brom hit back and was rewarded with an equalizer when Chelsea gave the ball away and Craig Gardner fired home from 25 yards (meters) in the 33rd minute.
Chelsea's pressure paid off in the 73rd minute when West Brom's Gareth McAuley turned the ball into his own net as he tried to intercept a low cross by Willian.
But victory slipped through Chelsea's grasp at the end, when James McClean pounced to score an equalizer in the 86th minute.
