The managerial merry-go-round has truly got going recently, with Sunderland convincing Dick Advocaat to return for another season and Newcastle sacking hapless first team coach John Carver, but the most ambitious move of all is perhaps West Ham's signing of former Croatia and Besiktas manager Slaven Bilic. The Croatian spent a year and a half at Upton Park during his playing career, establishing himself as a terrace favourite thanks to his dogged defensive displays and international quality. He certainly seems a stylistic improvement from the oft-criticised Sam Allardyce, a younger, internationally experienced manager to match West Ham's lofty ambitions - but only time will tell whether he has the substance to go with it. Despite a fantastic start to the 2014/15 campaign, fans of the East London side were left with a familiarly sour taste in their mouths following a dramatic slump in the second half of the season, resulting in an ultimately disappointing 12th place. With Bilic at the helm, they'll be looking to strengthen several areas in the squad - most notably up front, given the injury-prone nature of Andy Carroll, and at right back (although Carl Jenkinson could perhaps be tempted back for an extension of his loan deal). Here are ten players Slaven Bilic should include in his Upton Park revolution.
