Squad sheets: West Ham United v Bolton Wanderers

West Ham can only improve on their abject performance at Villa Park, where a 3-0 defeat let them off lightly. Avram Grant's main concern will be to restore confidence and discipline to a defence that all but surrendered. Scott Parker, as ever, is the crucial figure and his ability to link defence with attack will be the key this season, always assuming that the resolve not to sell him holds good. Bolton have already improved on last season, when they lost their opening three games, and will hope to build on a workmanlike 0-0 draw with Fulham.
