Chelsea have scored 57 final-day Premier League goals, the second-most in the competition’s history after Arsenal's 64. The Blues hold the record for the biggest PL victory on the final day, beating Wigan Athletic 8-0 to seal the title in 2009/10.
Watford have won 65 per cent of their Premier League points away from home this season (15/23), with only Crystal Palace in 1997/98 ever having a higher share (67 per cent). If they win this match Watford will set a new such record, while a draw would suffice for them to equal the Eagles' mark from that campaign.
Chelsea have never lost in seven Premier League home matches against Watford (W6 D1), scoring at least twice in all seven meetings.
Watford are yet to score a Premier League goal from outside the box this season. There have been only three occasions of a team going through an entire campaign without scoring from distance, with Watford already responsible for one of those (2019/20 – also Manchester City and Middlesbrough in 1995/96).
