WEST HAM boss Julen Lopetegui feels his side must be prepared to face a demanding challenge when they head to Leicester tonight for Ruud van Nistelrooy’s first game in charge.

Dutchman Van Nistelrooy has replaced Steve Cooper, sacked by the Foxes after just five months in charge, and watched on as his new side were thumped 4-1 at Brentford on Saturday.

The former Manchester United assistant coach and PSV Eindhoven boss will have had little time to work with the players as he looks to arrest a run of four defeats from the last five Premier League games.
