David Moyes has admitted that Manchester United are in for several players but doesn't know if he can bring them in before the transfer window closes.
So far this summer, Moyes has failed to bring in anyone significant, with attempts to sign Thiago Alcantara and Cesc Fabregas from Barcelona falling flat. However, the new manager is still confident of making additions.
The Scot told Sky Sports News: "I'm confident we will have players in.
"We are involved in several players we are looking at and that will continue. Will we get them before the deadline? I hope so, but we are working very hard to do so."
Moyes, who succeeded Sir Alex Ferguson at the helm of Old Trafford, did admit that he has struggled to assert himself in the transfer window but is working harder than ever.
He added: "This was always going to be a difficult window for me personally because I joined Manchester United on 1 July so it is giving you a short period to get to know the players and to get to know the market.
"Yes of course I was working on it during the summer but it is never the same until you have actually worked with the players and been around them.
"But what I do know is the group of players we have got are a great group of players - they won the Premier League last year.
"We have got lots of young exciting players - a lot of them played for England last night - so it is important that we focus on the players we have got at Manchester United and how well they have done last year.
"There is not much change so hopefully they will be able to continue the way they finished last season."
Moyes also admitted that he still speaks to Ferguson, who is now a club director, on a regular basis.
"I went to see him at his house and I speak to him quite regularly on the phone," he said. "It's good to have someone I can go to if I need any advice, especially at a club like Manchester United.
"He's great and he's someone I look forward to taking advice from in the future."
