Manchester United have suffered a major setback ahead of their pre-season showdown against Leeds United later today.
According to BBC Sport, Mason Mount has not trained since the Paris Saint-Germain game and is now unlikely to play against Leeds.
Mount took a knock to the foot during the opening minutes against PSG before being withdrawn after just 20 minutes.
Manager Michael Carrick insisted the substitution was purely precautionary, but this latest development will certainly raise concerns at Old Trafford.
United entered this transfer market with the aim of revamping their midfield after the departure of Casemiro.
Andrey Santos and Youri Tielemans were recruited last month but United clearly need another quality midfielder.
The Red Devils are back in the UEFA Champions League and will need serious squad depth to compete across four competitions.
Carrick has deployed Mount in the number eight spot this summer.
The £55 million star has looked increasingly comfortable in his new position.
He has impressed with his football intelligence and ability to connect the midfield with attack.
However, his troublesome injury record makes another midfield addition increasingly difficult to ignore.
The former Chelsea midfielder is an intelligent footballer, but recurring fitness problems have repeatedly prevented him from establishing himself at Old Trafford.
His absence could now open the door for Carrick to field a new midfield pairing of Santos and Tielemans.
He also attracted special praise from club captain Bruno Fernandes after his standout display against Atletico Madrid in Stockholm.
Tyler Fletcher could also be handed an opportunity after making significant strides over the past few months.
