West Ham's record against Stoke will be a source of inspiration to Zola. The Hammers did the double over the Potters last season and have not lost away to the midlands outfit since October 1983, a run that takes in six matches.The Londoners coped well with Stoke's direct style and aerial bombardment when picking up six points against them last campaign and Zola is backing his team to stand firm.West Ham have been the subject of takeover speculation this week, with former Birmingham owner David Sullivan linked with an approach to buy the Hammers.Sullivan has insisted the timing is not right but other buyers could soon come in for the club.Zola maintains these board issues are not his domain but recognises that an improvement in form on the pitch will make West Ham a more attractive proposition for potential buyers.Stoke midfielder Glenn Whelan is the only doubt for manager Tony Pulis as he prepares for the Barclays Premier League visit of West Ham.The Republic of Ireland international sustained a calf injury against Italy in a World Cup qualifier last weekend.Summer signing Tuncay Sanli, who played for Turkey on Wednesday, is edging closer to a first Barclays Premier League start after three substitute appearances.Pulis revels in the club's underdog tag and so is not entirely comfortable with being made favourites for the visit of West Ham.In the Potters' maiden Barclays Premier League campaign Pulis' team made a habit of being a thorn in the side of many clubs with greater top-flight experience.For me West Ham won't lose here.
