Moyes said: 'We are not ready as far as the squad goes, we want more players in. We let a few go in the summer - Andy van der Meyde, Lars Jacobson, Nuno Valente - and we have not replaced any of those players yet.
'If we want a run in Europe we need more players quickly. The search goes on, it has never stopped all summer and I am feeling a bit demented with it all now!
'Apart from a couple of clubs, the transfer activity around the country has been limited. But for us, to have finished fifth and reached a cup final, to improve on that costs a lot of money.
'But we don't have that money. So trying to find players who are cheap, don't want much wages and will come here to improve us, well, it is not easy.'
So far, Moyes has only brought in Brazilian striker Jo on loan from Manchester City and a clutch of untried youngsters who will be in the reserve squad.
He remains hopeful of a positive outcome in his bid for Arsenal defender Philippe Senderos, although the clubs are believed to be still some way from agreeing a fee.
Moyes said: 'We have a good team but what we do not have is back-up, and that is what we are trying to get.
