Manchester United management have concerns about the form of Bruno Fernandes.
The warning signs were there during Euro 2020 when the midfielder was dropped in favour of Renato Sanches due to his underwhelming displays.
A staggering 28-goal total in all competitions last season has been followed up with just four so far this campaign.
The Athletic says there are now 'nagging concerns' that Fernandes is running on empty after playing a huge amount of football over the past 18 months.
Since the start of last season, he has notched 94 appearances for club and country as United regularly call on him for game-changing moments.
That could now be taking its toll, with the Red Devils stumbling to a series of poor results in recent weeks which has put manager Ole Gunnar Solskjaer under serious pressure.
