But, a month later, Eddie Howe returned from Burnley, Bournemouth began part two of their extraordinary rise and the rest, as they say, is history.Chris Wilder has had a similarly monstrous impact since taking over the reins at his boyhood club four years ago.
The form of Wilson will be key in keeping Bournemouth in the Premier League this season, as well as enhancing is chances with the Three Lions at the end of it.
Since winning promotion to the top flight in 2015, Howe has kept the Cherries in the division.
He impressed with an elegant home debut against Bournemouth and the fans have an incredibly catchy chant for Berge, sung along to She's Electric by Oasis, which shows where the Blades' fans expectations are now: "He's Norwegian, next to Norwood and Fleck he's the reason, we'll be playing in Europe next season, his name is Sander Berge".
Indeed, the Blades have conceded only seven times in their previous nine league fixtures, and look well worth the 6/4 (2.50) odds to win to nil against a goal-shy Bournemouth.
That puts pressure on United's next game against Chelsea, in which a loss would put a major dent in their Champions League hopes.
"They're not one of biggest clubs in the Premier League but they work with young players and create a team. He's arguably the best post-war Sheffield United manager and this is comfortably the best Sheffield United team I've ever seen".
The sides shared a 1-1 draw at the Vitality Stadium on the opening day of the season, and you can get odds of 13/5 (3.60) on them cancelling each other out once again. We want to achieve something this season. We have to be mindful of it.
But on Sunday, Wilson made sure he left Southgate with no choice but to keep him at the forefront of his thoughts, looking alive to latch onto a rebound to give Bournemouth an early lead at Bramall Lane. The former Southampton striker has missed the last four matches with a foot problem but Wilder said he had been "back on the grass" this week.
