Bruce, captain when United first lifted the Premier League trophy in 1993, said: "That first title was so difficult because we had bottled it against Leeds the year before. It's quite incredible to think United hadn't won the league for 26 years and if they win here against us they will have done it 11 times since.
"It's no good asking me how he does it. If we knew we'd all be doing it. He has to be the No 1 manager of all time now. It's quite incredible. He has still got the hunger and that look - you know, the one that makes you go, 'uh, oh'.
"That '93 team was a terrific team. But in terms of depth, this squad is just mind-blowing. They can make all those changes without being any different. Success seems to last half a day with him and then he's back at work.
"He will want to finish above Liverpool in terms of league titles, and as far as the Champions League is concerned, Real Madrid maybe out of reach with nine but he will be wanting to be up there with the likes of Ajax, Munich and Liverpool.
"I don't think he has any intention of quitting at all. He seems to thrive on the pressure rather than fear it."
