Chelsea ended a three-game winless streak in the Premier League with an assured 2-0 victory at Hull City on Saturday.
Two goals in seven second-half minutes from Willian (61) and Diego Costa (67) put the game beyond the hosts as Antonio Conte’s men ended a miserable September on a high note.
The result condemns Hull to a fourth defeat in their last five top-flight games, while the Tigers remain without a win against Chelsea in nine Premier League meetings.
Isaac Success came off the bench to score Watford’s second-half equaliser and his first for the club in a 2-2 draw at home to Bournemouth.
The summer signing from Granada steered a header into the far corner on 65 minutes after fellow second-half substitute Josh King had beaten two players and smashed a low shot home to restore the Cherries’ lead.
The visitors had gone ahead during an impressive first-half display when Callum Wilson stole in front of his marker and flicked Junior Stanislas’ cross through Heurelho Gomes’ clumsy handling (31).
James Milner’s late penalty gave Liverpool a 2-1 win at Swansea on Saturday to extend their winning run to five games.
Leroy Fer gave Swansea the lead with a simple close-range finish early on, and Swansea should have been further ahead in the first half, but Borja Baston’s two unmarked headers were off target.
A brilliant solo goal from Dimitri Payet salvaged a point for West Ham as they and Middlesbrough both ended losing runs with a 1-1 draw.
Cristhian Stuani’s header early in the second half (51) put the visitors in front but a wonderful mazy run and finish from Frenchman Payet soon sftare (57) brought the sides level again.
From there, neither side looked like finding a winner and the ensuing stalemate did little to improve their recent records.
