West Ham are already weighing up potential successors to Slaven Bilic following their disappointing start to the season. Former Croatia national team coach Bilic is under scrutiny and the Hammers have begun drawing up contingency plans with only two rounds of Premier League games played. Co-owners David Gold and David Sullivan are known for their reluctance to make mid-season managerial changes and Bilic’s current contract is up at the end of the season, but they are wary of being dragged into another relegation battle after last season’s struggles. And a failure to oversee a quick upturn in results could leave Bilic in danger and force the Hammers hierarchy to reassess sooner.
