Moyes is also hoping loan signing Landon Donovan, who has joined for a 10-week spell from Los Angeles Galaxy, can also give the side a lift.
The 27-year-old United States international only started training with his new club this week, but because of the on-going injury situation Moyes is considering whether he should feature against Arsenal on Saturday.
"He has had a month's holiday off the back-end of their season and to put him back in after five days' training is not really the right thing to do, but the needs are at this present time that we might need to do that," said the Scot.
"When you take players from anywhere you just never quite know but he has been really keen.
"I hope the players see we have tried to bring in a proven international, who can play in several roles for us, who we hope can help us.
"We won't be able to tell that until he has featured in some of the games.
"It will be very difficult for any player coming from another country to deliver straight away but hopefully he can help us in some of the cups and the league.
"If it doesn't work for him then at least we've given it a go and tried it."
