Former United and Australia goalkeeper Bosnich told talkSPORT that he feels Moyes has to be given the tools to strengthen his squad this European winter if the famous club want to have any chance of success in 2013/14.
"You have to improve your squad every year if you're going to stay on the top.
"The Glazers, Ed Woodward or whoever is calling the shots, have really got to stand up in this January transfer window and give Moyes funds to get the players he really wants.
"This season is heading towards disaster. They might not finish in the top four. They really need to say, 'this season is salvageable, we might not win the title but we could finish in the top four but we need to identify big players, players of Manchester United's calibre and spend some money'."
