The Premier League champions have been ridiculed for a number of failures during the transfer period as the club strived desperately to recruit a creative midfielder of some repute before the deadline.
Maroaune Fellaini was the only signing of note for David Moyes before the transfer deadline, with the club previously having targeted candidates of a higher calibre - the most notable of which being former Arsenal captain Cesc Fabregas.
The Barcelona star was identified as the top target for Manchester United, who failed in a least two bids to bring Fabregas to Old Trafford and soften the blow struck by the retirement of Paul Scholes.
Ed Woodward, Manchester United's chief negotiator, drew extreme criticism for his inability to close a deal for Fabregas - or some other potentially key acquisitions - and Bosnich believes the club were not willing to offer enough money.
“I would hate to judge Edward Woodward too soon, everyone deserves an opportunity, but it is a different ball game altogether [to signing commercial deals],” he told talkSPORT.
“Sir Alex Ferguson has been doing business for 26 years at Manchester United and David Gill for god knows how many years. People trust them and know them very well. All of a sudden there's some news guys in town and there's lots of people out there who aren't going to deal with them until they know how they operate.
“When you start offering money for top players which is not enough, then the selling club is going to turn round and question whether you know what you're doing.
“If Barcelona have said that they want £50million for Cesc Fabregas, and you offer £46m, then you're going to shake them. They're going to turn around and say, ‘if you offer £48m we'll take it’. But if you offer so much below the odds then you are going to get people who question whether they know what they're doing.”
