New boss David Moyes and chief executive Edward Woodward have come in for criticism from the club's fans after they failed to land a series of high-profile targets throughout the window, as well as for their scattergun approach to the market on deadline day.
It has been confirmed they failed with bids for Atheltic BIlbao's Ander Herrera and Real Madrid's Sami Khedira, and failed to complete a loan deal with Madrid for full-back Fabio Coentrao. They did however manage to complete the £27.5 million transfer of Marouane Fellaini from Everton.
Now according to Goal, senior figures at Old Trafford will seek an explanation into what happened in the last hours before the transfer window closed at 11pm last night.
The website claims that Manchester United will use the international break to look back at the events of the summer transfer window, and seek answers as to why targets such as Cesc Fabregas, Thiago Alcantara and Leighton Baines slipped through the net.
The only other deal the Red Devils completed during the transfer window was for young full-back Guillermo Varela.
