Ole Gunnar Solskjaer wants three more signings before the end of the transfer window, according to various reports in the media.
The Norwegian manager made his first signing of the season when an agreement was struck to sign Donny van de Beek from Ajax. The 23-year-old Dutch international is set to form a midfield three with Bruno Fernandes and Paul Pogba, which may lead to some exits.
Because United still hope to strike a deal for Jadon Sancho, the club may have to sell some existing players in order to raise funds for any further transfer moves. Sancho should cost around £100 million, and so players like Jesse Lingard and Andreas Pereira could be set to leave.
Chris Smalling, Marcos Rojo and Phil Jones have also been linked with moves away from Old Trafford, with both Rojo and Smalling spending part or all of last season on loan at Roma and Estudiantes respectively. Solskjaer is known to want another central defender to partner Harry Maguire with Victor Lindelof only intermittently impressive.
Dayot Upamecano was rumoured to be in line for a transfer, but his release clause of around 40 million euros is only in play next season, though there is a belief at the club that a deal could be struck this summer.
United also want a right winger if they are not able to sign Sancho, and are also after a new striker to support Anthony Martial. Odion Ighalo has impressed at United after arriving on loan from China, but while he has extended his deal to run until January next year, he is only a temporary solution and a longer-term alternative is needed.
Raul Jimenez of Wolves is potentially an option, though at 29 he has a limited shelf life, though taking 18-year-old former Yeovil Town striker Devon Arnold on trial does seem a bit like going a bit too much the other way.
