Manchester United are determined to remain "financially disciplined and compliant with FFP rules" after football director John Murtough again said January would be a quiet transfer window.
Speaking to a fans' forum last month, Murtough gave an update on transfer plans but raised the spectre of Financial Fair Play as one reason why United were looking at a loan signing for a striker this month.
The club went over their initial transfer budget in the summer when they spent £225million on new players, including a £70m deal for Casemiro and an £85.5m move for Antony in the final couple of weeks of the window.
