The Scot has come under fire for his dealings in the transfer market during the summer, which saw him pay £4million over the odds for Maraoune Fellaini – their only major signing of the transfer window.
The criticism has appeared justified following United’s poor start to the season, which has seen them pick up seven points from a possible 15, and which has included defeats to arch rivals Liverpool and Manchester City.
Sunday’s 4-1 defeat at the Etihad has been particularly damaging for Moyes, but the former Everton boss has since come out fighting – whilst admitting his own frustrations.
Asked if he needed more players, Moyes said: ‘Maybe where we’ve got work to do is to bring players in, not for the squad, but to go right into the team. But that will happen.
‘Going back to that transfer window, we always said it was going to be a tough one and it was going to take a bit more time. So yes, it does mean I may have to take a few more blows.
‘I knew this was going to be the case because I was taking over from a great manager and it was always going to take time for me to change things.’
Moyes is adamant his side will improve however, and claims there may be more days of hurt as he tries to stamp his own style on the team.
He added: ‘You have days like we did on Sunday and there might be more because we are in a period where there will be transition.’
