Mark Bosnich has urged Manchester United boss David Moyes to spend money on new players this January.
The Red Devils currently find themselves seventh on the Premier League table, 11 points behind league leaders Arsenal, and out of the FA Cup following the weekend's 2-1 loss to Swansea City.
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.
"Man United's problems can be traced back to their lack of activity in the transfer window last summer," the former Aston Villa and Chelsea gloveman said.
"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'."
