Full Match - Aston Villa 6-1 BrightonSep 30
The Bramall Lane clash is the Premier League's first Yorkshire derby since 2001, when a high-flying Leeds side thrashed Bradford City 6-1 at Elland Road.
Hosts Sheffield United were last season's surprise package. At one point Chris Wilder's men were in serious contention for European football before eventually finishing in ninth - just two points behind Arsenal.
But their 2020/21 campaign has got off to the worst possible start. Successive defeats to Wolves and Aston Villa have left them winless and just one place above the relegation places.
Leeds meanwhile are showing no signs of rust following their 16-year absence from the Premier League.
Marcelo Biesla's men pushed champions Liverpool all the way in a seven-goal thriller at Anfield before notching their first top-flight points of the season in a 4-3 win over fellow Premier League new boys Fulham last weekend.
