A new dawn awaits for Manchester United after so many false ones post-Sir Alex Ferguson.

Replacing the club's greatest ever manager and, arguably, one of the very best to stand in a dugout anywhere was never going to be the easiest task. Some 11 years later, though, and United are no way near the levels they reached time and time again under the legendary Scot - but success or failure is never just down to one man.

Roy Keane, another iconic figure who needs no introduction at Old Trafford, is not exactly the go-to for Sir Alex if he ever wanted a glowing reference. However, before the infamous fallout - and the feud which has continued to this day - there was a mutual respect and ambition that infiltrated the United dressing room.

Relationships were compromised, but standards never were. The proof is in the pudding - or countless trophies.

Getting an insight into what it was really like at United is more accessible than ever. Keane, along with old United teammate, Gary Neville, and others The Overlap's ever-popular Stick To Football podcast, constantly regale stories, adventures and one or two bust-ups that made United such the force they were in the 1990s and 2000s.

But will Ruben Amorim finally be the man to recapture the glory days? Can he succeed where David Moyes, Louis van Gaal, Jose Mourinho, Ole Gunnar Solskjaer and recently-sacked Erik ten Hag ultimately failed?

If he does, he will have to iron out one unwanted in-house trend Sir Alex and Keane would have never stood for.

"I do think the players, obviously, get away with murder," Keane said in 2018 when Mourinho - who has more than given the thumbs up to United for appointing Amorim - was sacked by the hierarchy.

Keane added: "Just the way they hide behind the manager, Mourinho. Whatever you say about the players, they have thrown him under the bus. People have said Mourinho has been falling out with players, well you would fall out with players.

"That's the name of the game, players turn up overweight or players are not training properly and not producing. And then for some of them to down tools, you know, shame on some of them players.

"I'm not Mourinho's biggest fan, don't get me wrong, but I just can't tolerate footballers who hide behind agents, their pals in the media. A bit of a joke, really."

A penny for Ten Hag's thoughts? Let alone Mourinho.

Credit where it's due, Ten Hag - certainly initially - brought discipline and was uncompromising in his standards in dealing with high-profile situations involving Cristiano Ronaldo, Jadon Sancho and Marcus Rashford - who bucked the trend in that he remained at Old Trafford despite what may or may not have happened with Ten Hag.

However, on the training ground as Amorim gets to work, a certain harsh reality is unravelling, whether by design or chance, as an injury- and confidence-hit squad takes a healthier turn.

For all the qualities a manager must have to enjoy success, lady luck does play a part. United were hit harder than most with injuries during Ten Hag's reign and the Dutchman just couldn't shake off those woes with Tyrell Malacia, Luke Shaw, Raphael Varane, Victor Lindelof, Rasmus Hojlund and others giving him cause for concern in that sense - and that list is by no means exhaustive or particular.

By nothing more than coincidence, United could soon be fighting fit. They had seven doubts for their impending game against Ipswich - which sees Amorim take to the dugout for the first time - but each of those players do not expect to be missing for too much longer and United have also been handed a major boost by Kobbie Mainoo.

Ten Hag, for all his pros and cons, was rarely able to call upon his best XI - certainly with any regularity. Amorim, it seems, might be afforded that luxury within a couple of weeks if all goes to plan, but he would be wise to keep his clear warning from Keane in mind with the theme rather than any individuals, as such.

There's nowhere to hide when Keane is watching. Mourinho and Ten Hag know it all-too well.
