Arsenal's Premier League title hopes suffered a major blow with a 2-1 home defeat by Bournemouth, while Liverpool boosted their push for a Champions League place with a 2-0 win over Fulham on Saturday.
Bournemouth's 19-year-old Eli Junior Kroupi turned in a deflected cross at the far post in the 17th minute, before Viktor Gyokeres equalised from the spot in the 35th minute.
However, Bournemouth struck again as Alex Scott was played in by Evanilson and finished calmly past David Raya in the 74th minute.
Liverpool, meanwhile, remain fifth on 52 points, four ahead of Chelsea, with a victory that featured teenaged winger Rio Ngumoha becoming the club's youngest player to score a Premier League goal at Anfield.
Mohamed Salah doubled the lead with a first-time finish into the far corner after 40 minutes, as Liverpool ended a run of three straight losses in all competitions.
