Since taking over in the summer, Moyes has struggled to add much quality to the United squad and that has taken its toll with the champions languishing outside of the European spots.
A trip to in-form Chelsea is ahead of Moyes and his side today and a negative result could see them slip 12 points behind the Blues and a whopping 14 behind leaders Arsenal.
Without key men Wayne Rooney and Robin van Persie, United are struggling to compete at the right end of the Premier League and so Moyes was expected to dip into the transfer market this month.
However, the former Everton boss is yet to make a new signing although he claims this is not because players don’t want to join the club.
“Manchester United are not only the biggest club in this country, but the biggest club in the world,” Moyes said.
“There is no issue about signing big players – not by my trips and the things I am hearing.
“The number of big players wanting to join Manchester United is incredible.
“Maybe players want to go to other clubs for the money, but if you ask them where they really want to be, which club they really want to wear the badge of, they want to wear the badge of Manchester United.
“It’s because of what this club stands for in world terms – everything about it.”
