Sheffield United host Liverpool at Bramall Lane on Saturday for the first time in the Premier League since opening up their campaign in 2006.
On that day, the Blades were under another boyhood fan-turned manager in Neil Warnock.
And after the hour mark they were good value for a 1-0 lead, given to them by summer signing Rob Hulse after 52 seconds of the second half.
However, what would occur in the 68th minute was perhaps one of the most controversial non-events in Premier League history, one which fans continue to pore over whilst watching Premier League Years now.
Rafa Benitez’s side were looking rather uninspired until Steven Gerrard took possession, played a one-two with Robbie Fowler on the edge of the penalty area, and accelerated into the box.
Across came a rash sliding challenge from United captain Chris Morgan, seemingly hurdled by Gerrard.
He landed, unbalanced, scraped a tame shot straight at Paddy Kenny and, hit the deck.
Referee Rob Styles blew his whistle, pointed to the spot and opened up a whole can of worms over tackling and intent.
Fowler tucked home the spot-kick and Liverpool escaped with a share of the spoils, but Warnock was left fuming over the decision.
“I didn’t think it was a penalty. There was no contact,” roared Warnock.
“Apparently the ref has said there was intent, so that means there are going to be a lot of free-kicks given!”
Indeed, under-fire Styles took the unusual step of facing the cameras post-game and explaining his decision.
“I saw the Sheffield United player to come in and make side contact with Steven Gerrard.
“Moving at that pace it’s always going to put him off balance and he subsequently lost the opportunity to score.
“There was no advantage so I gave the penalty. I certainly thought there was contact.
“Only slight contact perhaps, but Gerrard lost the opportunity to score a goal and I am allowed to wait and see whether an advantage accrues before blowing the whistle.”
“I intend to ask him about that,” Warnock said, when told of Styles’ declaration.
“He’s bound to have an answer, referees always do, but he might not have thought it up yet.”
The situation remains in question to this day, given the Laws of the Game which state an indirect free kick should be given if a player “impedes the progress of an opponent without any contact being made”.
For Warnock, it was just another day at the office.
The following April, he was left furious with Styles again, having been denied a penalty at Old Trafford, all but accusing Styles of being scared to give a penalty against Sir Alex Ferguson.
“Rob said he couldn’t 100 per cent give a penalty. But surely he should have looked at the linesman so between them they get it right.
“Why can’t you consult the linesman? What is the point in him being there? I don’t understand it. At times, you need to use your linesman as another pair of eyes.”
The Blades ended up being relegated the following month, following the tale of Carlos Tevez.
Win, lose or draw against Jurgen Klopp’s Reds, Chris Wilder’s men will be looking for a different outcome in eight months time.
