Manchester United's Ed Woodward has admitted in private that he and David Moyes came up short in the transfer window this summer, reports the Daily Mirror.
Woodward replaced the long-standing chief executive David Gill this summer to complete a wholesale change with Sir Alex Ferguson also vacating the manager's position.
New manager Moyes targeted a new left-back as well as two central midfielders to reinforce the Premier League champions ahead of their title defence.
However, Marouane Fellaini was the only major addition to the squad, moving to United in a last minute transfer deadline day deal for £27.5m.
The lack of transfer activity has led to criticism from United fans, with some even calling for Woodward to step down just months after his appointment.
The Mirror has now reported that Woodward has privately accepted that he and Moyes failed to get to grips with their new roles over the summer.
Woodward is said to have taken criticism from fans to heart after struggling in his new role as executive vice-chairman but does accept he could have done more.
The failed attempts to bring in a creative midfielder was compounded by a botched deadline day move for Athletic Bilbao midfielder Ander Herrera.
They also couldn't broker deals for Fellaini's team mate Leighton Baines or Real Madrid outcast Fabio Coentrao.
Despite these failures, there is, however, a feeling that retaining Chelsea target Wayne Rooney was a major achievement for the club.
However, with their Manchester rivals City conducting efficient transfer business along with rivals Tottenham, Liverpool and Chelsea; there is a feeling behind the scenes at Old Trafford that Woodward and Moyes could have done much more to strengthen the squad.
