West Ham United goalkeeper Robert Green admits the worst thing to come from his error-prone display against Bolton was that it ended manager Gianfranco Zola's unbeaten run since taking over.

"Being responsible for the start of the downfall [the first league defeat under Zola] is the biggest disappointment," he said. "I'll go back to the training ground and work on catching. If it had come after winning 5-0 and in the last minute, then you try and take it with a pinch of salt."
