Ralf Rangnick revealed Manchester United's preparations against Leicester were disrupted before and during the draw as substitute Jesse Lingard was sick and unable to come on.
Rangnick had intended to start Cristiano Ronaldo up front but the Portuguese felt unwell on Friday and was ruled out on Saturday morning after he was visited by the club doctor, so Bruno Fernandes started as a 'false nine'.
Lingard and Juan Mata were United's remaining attacking options to come on after the introduction of Marcus Rashford but Lingard was discounted altogether as he was vomiting during the 1-1 draw.
