The Reds manager addressed the media ahead of the Bank Holiday fixture against Chelsea and was inevitably asked about the latest on the window.
"There is a need to do it," explained Moyes, when quizzed on introducing new faces to the title-winning squad. "But there is no pressure to do it.
"We've been talking about it since I took the job on 1 July. I have an idea of where I'd like to strengthen and what we need to do. But we won't do it because people like you tell us we should be signing players. We'll do it because we think it's the right thing to do. If the right players are available then great, but, if not, the first thing we'll do is encourage our own young players in the squad to do as well as they did last year.
"There is a possibility [we won't sign anybody] but the plan is we bring in one or two if we can. I think there is [value out there] but we have only targeted certain players and don't have a big, big list. There are only certain quality players we want to bring to the club."
The manager also rebuffed another question regarding Chelsea's interest in striker Wayne Rooney ahead of Monday's game.
"We've told you, haven't we?" he asserted. "I hardly need to repeat it again. It doesn't need to be said."
