Manchester United are concerned about their star midfielder Bruno Fernandes.

The Portuguese playmaker has been a goal and assist machine since signing from Sporting CP in January.

But the Red Devils are concerned about his mental and physical condition, per O Jogo.

Fernandes came off at half-time in United's 6-1 loss to Tottenham in the Premier League before the international break.

The player has been involved in nearly every United game since the COVID-19 hiatus.

The club may be concerned he is too fatigued to contribute to his best ability this season.

Managing his minutes will be key, and the signing of Donny van de Beek may have been made towards that end.
