Manchester United players are reportedly worried about how Paul Pogba will react to being taken off penalty duties in favour of Marcus Rashford.
Rashford took and scored a spot kick in United's 4-0 demolition of Chelsea in their opening Premier League game.
In the Red Devils' next league fixture, Pogba was fouled by Conor Coady in the box against Wolverhampton Wanderers at Molineux and asked to take the penalty himself.
With the scores level at 1-1, the Frenchman saw his effort saved by Rui Patricio, and United ultimately failed to win the game.
Following the incident, head coach Ole Gunnar Solskjaer is thought to have announced to the dressing room that Rashford must take all further penalties when he is on the pitch, according to The Sun.
There are those within the United camp who fear that this decision may cause Pogba, whose future is still uncertain, to push through a move to a top European club before their transfer deadline closes.
