Manchester United's enigmatic manager Jose Mourinho has spent heavily since joining the club in May 2016.
The former Chelsea coach has splashed out a whopping £285m on new signings and broke the world transfer record to bring in Juventus midfielder Paul Pogba.
Neymar's €222m transfer from Barcelona to PSG this summer shattered that record.
The Red Devils are currently eight points behind rivals Manchester City following Sunday's 1-0 defeat away at Chelsea.
Despite winning two trophies since taking the reins, Mourinho has recently been criticised for the negative tactics he has employed.
“If a team defends badly, concedes five goals but attacks phenomenally well and scores six, then that’s absolutely beautiful and amazing,” Mourinho said in October.
“I know my team cannot score four, five or six every match. I know that, especially with a certain profile of matches, it is difficult for us to score a lot of goals. We have to try to find balances and I’m really happy with what the team is doing. Critics, critics – no problem.”
Man Utd board's position on January transfers
Despite spending £140m over the summer, Manchester United fans may well be expecting some new arrivals to freshen things up in January.
However, according to the BBC, the United board are planning to inform the Portuguese manager that signings can only be made if players are offloaded.
The Manchester United hierarchy are reportedly looking to control costs.
Since Mourinho took charge, the Reds have received less than £50m from player departures - whilst £285m has been spent on player arrivals.
The most recent financial results, released in September, showed Man United's wage bill had risen by 13.5% to £263.5m.
Large sums of money have spent on Romelu Lukaku, Nemanja Matic, Victor Lindelof, Paul Pogba, Eric Bailly and Henrikh Mkhitaryan.
Who could leave in January?
Signed for £30m from Southampton from Louis van Gaal, Luke Shaw is considered the most likely to leave in January.
The young English full-back is yet to start a game this season and it doesn't take an expert to realise that Mourinho is not a fan.
It would be a major surprise if any other member of the first team squad was sold in January.
