Manchester United have reportedly expressed concerns that they may struggle to complete deals over the January transfer window.

Ole Gunnar Solskjaer's side is in desperate need of reinforcements following a poor start to the 2019-20 season which sees them sitting two points above the relegation zone.

Supporters have strongly demanded that United improve their midfield and attack following the club's failure to secure replacements for Marouane Fellaini, Ander Herrera, Romelu Lukaku and Alexis Sanchez over the past year.

According to Manchester Evening News, the United hierarchy are doubtful over the club's ability to secure transfers in January, which they view as a 'difficult' time to complete deals.

There is a fear that, due to the club's situation and the time of year, prices for players will be considerably inflated.

However, the Red Devils appear to have made progress in their pursuit of Mario Mandzukic, who could join the club for just £9m.
