Manchester United will reportedly not be able to consider making another new signing unless they raise funds by letting players move on before the end of the transfer window.
Axel Tuanzebe, Andreas Pereira and Brandon Williams have left Old Trafford on loan this summer, but the club have not sanctioned any permanent exits in exchange for transfer fees.
Eduardo Camavinga of Rennes, and Atletico Madrid pair Saul Niguez and Kieran Trippier, are among those thought to be of interest to the Red Devils before the window closes.
However, according to ESPN, the 20-time English champions will not be able to firm up their interest until players are moved on in order to raise funds.
The report claims that West Ham United are still keen on a deal for Jesse Lingard, but it remains to be seen whether the Hammers are capable of matching Man United's asking price over the next week.
Ole Gunnar Solskjaer's side have signed both Jadon Sancho and Raphael Varane this summer, while Tom Heaton has returned to the club on a free transfer to boost their goalkeeping options.
