Match preview
Ruud van Nistelrooy begins his reign as Leicester manager by welcoming the boss under huge pressure as Julen Lopetegui's West Ham visit the King Power Stadium.
Van Nistelrooy takes over shortly after the sacking of Steve Cooper, and Lopetegui could be the next manager after Saturday's 5-2 home defeat by Arsenal.
For all their disappointment since the Spaniard replaced David Moyes, the Hammers are actually yet to lose back-to-back games in the Premier League this season, although they have won just four of their 13 games in total.
The Foxes are just a point above the relegation zone after Saturday's 4-1 defeat at Brentford, but Van Nistelrooy will be looking to extend his 20-game unbeaten run as manager, which stretches back to his time in charge of Manchester United and the in charge of PSV Eindhoven.
