Manchester United's players are becoming increasingly concerned at the managerial void at Old Trafford as their season continues to unravel.
United's 4-1 loss at Manchester City on Sunday was only their second defeat under interim boss Ralf Rangnick.
However, they have won just eight of the German's 18 games in charge, including none of the last three.
Meanwhile, BBC Sport also understands England striker Marcus Rashford is unsure of his Old Trafford future.
Rashford still wants to play for United and has another full season left on his contract - plus the option to extend until 2024.
