Many expect Solskjaer to be busy one way or another this month with the transfer window open again.
Though the Red Devils may need to bring funds in before splashing out, with the Premier League giants potentially selling a number of their players.
And, using valuations from Transfermarkt, United could make £40m by selling just six stars.
Goalkeeper Sergio Romero appears certain to end his Old Trafford career soon, and he is reportedly worth £1.8m.
Elsewhere, former regular Jesse Lingard is yet to make a Premier League appearance this season and United could rake in £9m by offloading the 28-year-old.
The same can be said of Phil Jones, who is worth £5.4m, with the England defender struggling with injuries.
Diogo Dalot and Andreas Pereira are both currently out on loan, to AC Milan and Lazio respectively.
Though United could bring in £20m by selling that duo this month with their deals scheduled to run until the end of the season.
Timothy Fosu-Mensah has not featured in the Premier League since the opening day of the campaign, and is another that United may look to sell.
And Transfermarkt’s valuation of £3.6m could tempt plenty of clubs into approaching for the 23-year-old defender.
United executive vice-chairman Ed Woodward has said on transfer plans: "We are getting closer to those objectives as the squad continues to develop following the arrivals of Bruno Fernandes, Donny van de Beek, Alex Telles and Edinson Cavani.
