Manager David Moyes says Manchester United "need" to make signings but are not under pressure to bring players in.
The Scot, whose team face Chelsea on Monday, wants new faces but maintains there is no need for panic over the lack of positive transfer news.
"There is a need to do it but there's no pressure to do it," Moyes said.
"It's something we've been talking about since I took the job on 1 July. I have an idea of where I'd like to strengthen but we won't do it because people tell us we should be signing players.
"If the right players are available, 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."
Moyes reiterated United's stance that Wayne Rooney will not be sold to Chelsea despite Blues manager Jose Mourinho suggesting his club will make a third bid for the England striker after Monday's match.
Although United have struggled to bring in new players, when asked if he believed there was value in the transfer market, Moyes replied: "Yes, I do, but we've only targeted certain players.
"We don't have a big, big list because there are only certain quality players we want to bring in to the club. The plan is we'll bring in one or two if we can."
Ahead of Monday's meeting at Old Trafford, Moyes also spoke highly of Mourinho.
"I am looking forward to seeing him again," said the former Everton boss.
"He is probably the best of the young, modern coaches in the world. He is the one who has had the most success. He deserves all the plaudits he gets."
Mourinho has similarly spoken of his high regard for Sir Alex Ferguson's successor, telling reporters on Friday: "I think he's going to do very well.
"I hope he doesn't win everything and he will leave something for the others, but he's in fantastic condition."
