Chelsea boss Frank Lampard has been left angered by his side's poor defensive showing in the pulsating 3-3 draw at West Brom.
His new-look team were dismantled in the first half with the Premier League newcomers reaching the interval with a shock three-goal lead. Callum Robinson struck twice and Kyle Bartley inflicted further misery at the far post.
All three efforts were avoidable and Lampard, despite the last-gasp fightback to secure a point, has rued the manner in which the west London outfit squandered their hopes of securing a win.
