The ex-Red Devils shot-stopper has recommended that the club's owners should give David Moyes as much money as he needs to save the faltering seasonMark Bosnich has urged former club Manchester United to spend big in January if they are to save their season and have any chance of retaining the Premier League.
United are currently seventh in the Premier League - winning just half of their opening 20 games - and were knocked out of the FA Cup by Swansea City on Sunday on home turf.
And former goalkeeper Bosnich believes that the Red Devils’ manager David Moyes will have to open up the cheque book if they are to claw back the 11 point deficit on leaders Arsenal.
"Man United’s problems can be traced back to their lack of activity in the transfer window last summer," the Australian told TalkSPORT. "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.'"
Bosnich spent two spells at the Old Trafford outfit, playing a total of 33 times under Sir Alex Ferguson, whilst also spending time at fellow Premier League clubs Aston Villa and Chelsea.
