Manchester United have defended their summer transfer activity in a letter to supporters.
Despite being linked to a host of big-name players during the transfer window - including Cesc Fabregeas, Thiago Alcantara and Ander Herrera - the Red Devils ended up signing Uruguayan right-back Guillermo Varela and Moyes' former player Marouane Fellaini, who cost £27.5m after his buyout clause expired.
But United have said they had two priorities this summer: to keep Wayne Rooney at Old Trafford and to sign a midfielder - both of which were achieved.
The United letter states: "The club had two main priorities for the transfer window. The first was to keep Wayne Rooney. He is a world-class player and the manager is very keen to have Wayne as a key part of the club's drive to retain the Premier League trophy. That aim was fulfilled.
"The second priority was to add a midfield player, and the capture of Fellaini has met that need.
"Add to that the fact that Wilfried Zaha is a new signing and that the manager has added the highly-rated young player Adnan Janazaj to the squad and the team does in fact have a different feel to it than the one that finished last season."
United have also pointed to the fact that they have tied down Portuguese winger Nani to a long-term contract, although there was an admission that they were keen to bolster their squad further before the start of September.
"Additional resources were there to add to that but it was not possible to agree with other clubs for the right players to leave," the letter continued. "The key point there is that the players we buy have to be the right ones for Manchester United; not just any player.
"The club has always backed the manager in the transfer market, as Sir Alex has said on many occasions and it will continue to do so. The club has demonstrated its belief in, and commitment to, David Moyes through the award of a six year contract.
"Allowing him to shape the future Manchester United team is a long term project not an eight-week panic. He must be given time to assess his new squad and come to his own decisions on which players he feels will strengthen it."
