Ralf Rangnick spoke with Anthony Martial about his comments claiming the Manchester United forward refused to be selected for their Premier League match at Aston Villa.
Rangnick said after United's 2-2 draw on Saturday, Martial, 26, had declined the opportunity to be named in the squad in the absence of injured duo Marcus Rashford and Cristiano Ronaldo.
Premier League clubs are permitted to name a maximum of nine substitutes and United only named eight at Villa Park - with two of them goalkeepers Dean Henderson and Tom Heaton.
