Manchester United's squad needs £200m worth of new players, according to one former managing director of a Premier League club.
Speaking to talkSPORT, ex-Liverpool MD Christian Purslow said he believes David Moyes must spend between £150m and £200m on five or six new players in the summer to get United up to speed.
The defending Premier League champions face a battle to even qualify for next year's Champions League competition. They currently sit seventh in the table, 11 points behind fourth-placed Liverpool.
And Purslow thinks the United squad needs a thorough overhaul as a 'starting point'.
"They now need to invest huge amounts of money," Purslow told talkSPORT. "They need around £150m-£200m worth of talent, that's five or six £25m players.
"That isn't a guarantee of success, but it's a starting point. The messaging coming out of Old Trafford suggests they will go very big this summer."
United executive chairman Ed Woodward has confirmed Moyes will have plenty of money to spend this summer - even after United splashed out £37m on former-Chelsea playmaker Juan Mata.
But Purslow thinks United may struggle to attract that calibre of player again if they fail to qualify for the Champions League.
"The issue is attracting world class players to Manchester United to play in the Europa League."
It could be a transitional summer for United, with Nemanja Vidic already one confirmed high-profile exit. Patrice Evra is also out of contract at the end of the season, and could be another to quit the club.
