Australian shotstopper Bosnich first arrived at Old Trafford in 1989 aged just 17, but failed to make much of an impact and headed home to Sydney United. His stay in Australia didn't last long though, as Aston Villa swooped to bring him back to England in 1992 aged 20.
After over 200 appearances for Villa, Bosnich earned a move back to United in order to be Peter Schmeichel's successor, but lost his place to Frenchman Fabien Barthez shortly after. He ended up with Chelsea, but his career in England ended in controversy after a failed drugs test.
Now retired, Bosnich is able to cast his eye over United's current predicament, and whilst he believes that manager Moyes is a great person, the results just aren't coming and poor results against Olympiacos in the Champions League and the Premier League home game against rivals Manchester City could lead to Moyes' sacking by next week.
"David Moyes is a wonderful man but things have gone from bad to worse," Bosnich said. "They've got big problems. You can see it out on the pitch. The two games (against Olympiakos and Manchester City) are huge."
"The West Ham match will take care of itself, but the results against those two will determine whether David Moyes stays at the club.
"If we see another two abject performances, especially in the derby, I don't think the board will have any choice but to appoint someone else," he concluded.
