Hull City was the promoted club that won its 2026–27 Premier League opening-weekend match by the largest margin.
Hull defeated Manchester United 2–0, a two-goal victory. Coventry City, another promoted club, lost 3–0 to Arsenal, while Ipswich Town beat fellow newcomer Sunderland 2–1. Comparing those results makes Hull the promoted winner with the largest winning margin.
The comparison includes only clubs promoted for the 2026–27 season. Sunderland was also promoted, but its 2–1 defeat to Ipswich means it was not a winning club in this comparison.
Hull’s result came at home on Saturday, 22 August 2026. It was the club’s return to the top flight after nine years away, so the margin added to the significance of its first match back.
The answer is not Arsenal, despite Arsenal recording the largest victory involving a promoted opponent. Arsenal were the defending champions, not a newly promoted club. The wording therefore requires comparing the promoted teams’ own results rather than simply identifying the biggest scoreline.
