While Rooney's name will naturally dominate tomorrow's headlines after his winning goal, Everton fans were quick to point out the performance of another man making his Toffees Premier League bow.
Everton host Stoke on Saturday to kick off their league campaign before also hosting Hajduk Split in their Europa League play-off next Thursday.
It was the 31-year-old striker's 199th Premier League goal.
Indeed, Ryan Shawcross embarrassingly fired past his own goalkeeper from Seamus Coleman's goalbound effort and, for a brief period, it seemed as if the goal would be ruled out for offside.
Romelu Lukaku can open his Manchester United account by scoring first against West Ham tomorrow at odds of 5-2.
Rooney dropped deeper into midfield in a bid to spark his team into life and immediately began to control the tempo, drawing a booking for Allen when he wriggled clear of the Stoke midfielder, who responded with a blatant tug.
"It doesn't get much better".
Everton midfielder James McCarthy will miss out the Premier League opener against Stoke City as he continues his recovery from a knee injury.
Stephen Ireland (leg) and Ibrahim Afellay (knee), are definitely out of Saturday's game. They have brought in Kurt Zouma on loan and Darren Fletcher but they look weaker heading into this campaign.
Who do you think should be in the starting XI versus Stoke?
Everton's net spend is, in fact, still barely over £1 million, although £50 million-rated Gyfli Sigurdsson, and another big-name striker, would greatly increase that figure if Koeman signs them before the window closes. The Dutch manager has already signed the likes of Jordan Pickford, Davy Klaassen and Henry Okeyuru in a bid to bolster his side as they look to improve on their last season's 7th placed finish. We are stronger than last season but being stronger than last season does not mean you will win against the big six because they also will be more strong.
Only once in Mark Hughes' four seasons as boss have the Potters got three points on the board in August and that was in 2013.
Expect defences to come out on top from this encounter, with the Toffees edging it by the odd goal.
