For the first time since 1999, Nottingham Forest hosted a Premier League game as they welcomed West Ham to the City Ground on a scorching hot day in the East Midlands.
The Reds were awarded all three points thanks to a goal by Taiwo Awoniyi in stoppage time in the first half, but the contest was not without controversy.
VAR was used multiple times, as both teams had goals disallowed, and Forest worked extremely hard for their win.
Here are four things that we learned on Sunday.
Dean Henderson impressed in front of Gareth Southgate
Dean Henderson arrived at the City Ground with a point to prove.
The 25-year-old left Manchester United on loan in search of first-team football, hoping to impress Gareth Southgate ahead of the World Cup this winter.
The Forest goalkeeper will be pleased that he was able to put in an outstanding performance while the England manager was present.
Henderson has made several impressive saves so far in his short time at Forest, and some of the saves he made against West Ham were particularly eye-catching.
Saïd Benrahma's effort outside the box resulted in the first significant save, which forced the ball wide so that Harry Toffolo could clear it.
The second save came from a point-blank header from Thomas Soucek following a thunderous strike against the bar from Pablo Fornals.
Declan Rice's penalty was the final big save. With Forest leading 1-0 in their first Premier League home game since 1999, the goalkeeper stood up to make a huge save to keep his team's lead.
During his team's victory, Henderson completed four saves, four high claims, two clearances, and seven long balls.
Neco Williams looks to be the perfect Djed Spence replacement
Djed Spence was one of Forest's key players in the Championship last season, so when he transferred to Tottenham Hotspur, Forest had to find a replacement right away.
Arriving from Liverpool, Neco Williams put on a performance deserving of the man of the match award in his second game for Forest.
The Welsh international had the most touches (76) and completed the most duels (9), tackles (6), and successful take-ons (2) of any outfield Forest player.
The 21-year-old also had the most shots in the game (4) and created the most chances (2) for Forest.
It was critical for Forest to sign a right wing-back who could defend confidently while also attacking enough to pose a real threat, and Williams has demonstrated both abilities in his second game in red.
From Trent Alexander-Arnold-esque passing to goal line clearances, Williams delivered an all-around wing-back performance that his new manager, as well as Forest fans, will be pleased with.
Benrahma a shining light on a miserable afternoon for West Ham
Benrahma was perhaps West Ham's best player in this game, despite the fact that West Ham are reportedly open to offers for him.
Although occasionally unreliable, the forward proved his value against Forest. He appeared sharp the entire match and was direct and speed pacy.
Prior to his thundering free-kick hitting the woodwork, the Algerian caused Dean Henderson to make a significant save and even had a goal disallowed.
Benrahma presented a significant threat to Forest's back line during the game by completing four dribbles and recording four key passes. The 27-year-old contributed on defence as well, winning seven ground duels.
Before this game, the Hammers might have been open to offers, but Benrahma's performance proved that he will be helpful to the teams' pursuit of Europe this year, even if it is from the bench.
A quiet day for Jarrod Bowen
The attacker didn't pose any problems for Forest at all, despite having 22 goal involvements in the Premier League last season.
Bowen misplaced all five of his attempted crosses and lost possession of the ball 15 times.
Only 15 of his passes were successful during the whole game, and the 25-year-old failed to get a shot on goal or create any significant chances.
The attacker put on a similar display against Manchester City, and while that can be expected against the league champions, Bowen will need to be at the top of his game to help West Ham qualify for Europe once more this year.
