Deception by simulation
From this season on, a three-man panel consisting of a former player, a former manager and a former match official will independently review on the Monday after games. Any player whom the three-man panel unanimously decide has caused an opponent to be sent off or has won a penalty as a result of deceiving the referee by will be charged by the Football Association with "Successful Deception of a Match Official" which carries a penalty of suspension for two matches. Everton striker Oumar Niasse became the first Premier League player to be punished under the new rule.
Manchester City were confirmed as Premier League champions following Manchester United's 0–1 defeat at home to West Bromwich Albion in the 33rd round. Manchester City had started the Premier League season with an away win over Brighton & Hove Albion in August. After a draw against Everton, Manchester City won eighteen games in a row. During this time they secured first position and held it for the remainder of the season. On 7 April, Manchester City lost to Manchester United in the local derby, in which a win would have secured their position as champions. The following week, Manchester United lost to bottom club West Bromwich Albion, and Manchester City defeated Tottenham. These results ensured Manchester City held an unassailable lead with five games left.
Defending champions Chelsea started the season badly, losing their opening game to Burnley 2–3; a win at one of the title favourites, Tottenham, in their second game seemed to get their defence back on track, but results in September, including losing 0–1 to Manchester City, left them six points behind the leaders in fourth place. They failed to show the consistency of the previous season, and finished in fifth place. Manchester United started the season strongly winning their first three games without conceding a goal and led the table until mid-September. However, following convincing wins against Liverpool (5–0), Watford (6–0) and Crystal Palace (5–0), Manchester City went top of the league in September and remained there for the rest of the season. During the campaign Manchester City broke and set several new club and English football records. They established national records in consecutive away (11) and overall (20) victories in all competitions; set a new English record for consecutive league wins (18); equalled the Premier League record for consecutive away league wins (11) and set club records by achieving 28 consecutive games unbeaten in all competitions; 30 consecutive games unbeaten in the league; 20 consecutive home wins in all competitions; and winning 14 away games in a season. They won their fifth English league title, and completed their second league and League Cup double in four years.
Arsenal had a poor season, finishing sixth overall. Long-serving manager Arsène Wenger announced his departure from the club on 20 April 2018. Their final home game was an emphatic 5–0 defeat of Burnley which guaranteed qualification to the group stage of the Europa League.
Despite the defeat, Burnley finished in seventh place, their best finish in English football since . This meant they would be entered into the second qualifying round of the Europa League, their first competitive European football campaign in 50 years. Their strong finish led to manager Sean Dyche and defender James Tarkowski being nominated for the Premier League Manager of the Season and Premier League Player of the Season awards respectively.
Stoke City were the first team to be relegated to the EFL Championship when they lost 1–2 to Crystal Palace in their penultimate game. Although Stoke were only three points from safety with one game remaining, fellow strugglers Swansea and Southampton still had to play each other, meaning that Stoke would be unable to catch both of those teams and finish fourth from bottom. The game between Swansea and Southampton ended in a 1–0 away win for Southampton, which also meant that despite a five game unbeaten run, West Bromwich Albion became the second team to be relegated to the Championship on 8 May 2018. Following their 1–2 defeat at the hands of Stoke on the final matchday, Swansea City were also relegated.
