Chelsea's reserve goalkeeper Ross Turnbull had a terrible outing at Amsterdam as shallow concentration and poor goalkeeping cost his team their match against Ajax.
A howler from the 25-year-old former Middlesborough shot-stopper gave Ajax a 3-1 win against the 2009-10 EPL champions who were playing well below their full strength.
The Dutch league outfit opened the scoring when a cross from Rasmus Lindgren created havoc in the Chelsea box and youngster Jeffrey Bruma diverted via Turnbull's arm. The Blues' reacted swiftly and levelled back with a fine strike form impressive youngster Daniel Sturridge.
But then a long ball from Ajax goalie Marteen Stekelenburg caught Turnbull sleeping. Chelsea's third-choice goalkeeper lost possession of the ball as he moved out of his area and misjudged the ball's jump. He watched in horror as Ajax's striker Siem De Jong slot home Ajax's second goal of the day.
An under-strength Chelsea, captained by Essien, fielded a relatively young team who failed to get back their rhythm after the goalkeeper shocker as Ajax continued to put pressure on the West London outfit.
Korea's Suk Hyun-jun put the final nail in Chelsea's coffin as he scored the third goal from close range and effectively ended Chelsea's undefeated streak so far.
The Middlesborough goalie is being seen as the prospective deputy for the Blues' first-choice goalkeeper Petr Cech. But today's goof-up is going to put a question mark on his credibility and might even affect his efforts to start for the "Double-winning" Blues as the new season nears commencement.
