West Ham 4-2 Burnley: Anderson double downs Clarets
West Ham manager Manuel Pellegrini said Felipe Anderson put in a "massive" performance as his two goals helped the Hammers beat Burnley.
The Brazilian midfielder joined the east London club from Lazio for £36m in July, but has struggled for consistency thus far, scoring just one goal before Saturday's game at London Stadium.
Pellegrini even said Anderson was "bad" in West Ham's Carabao Cup defeat to Tottenham, in which he was replaced by Robert Snodgrass at half-time.
"I said before the game that maybe some players need more time to adapt to the league, but his commitment has always been 100%," said Pellegrini.
"I talked a lot with him, and there was never a chance of him not playing. He knew from the beginning that despite playing bad against Tottenham, he was going to play. It was a massive performance."
The Hammers opened the scoring when Arnautovic dispossessed James Tarkowski before racing clear and firing home before Johann Berg Gudmundsson slotted home to equalise just before the break.
The hosts then retook the lead when the excellent Anderson curled a shot past Burnley keeper Joe Hart before second-half substitute Chris Wood's thumping header hauled the visitors level again.
Anderson, who was at the heart of everything West Ham did well, scored his second of the match six minutes from time, capitalising on some sloppy Burnley defending.
Hernandez completed the victory in injury time with a fine dinked finish which finished off a move started by Anderson in midfield.
It was a deserved victory for Pellegrini's side, whose previous victory was over Manchester United on September 29, are now 13th in the table two places above the Clarets.
Burnley, who have now lost six of their past nine games against West Ham, had Hart to thank on several occasions, with the former England and Manchester City goalkeeper saving well to deny Arnautovic either side of the break.
Anderson spearheads Hammers victory
Despite a winless October, the Hammers dominated throughout, slicing through Burnley at will, with Anderson the key player.
The 25-year-old Brazilian took more touches (103) and played more passes (75) than anyone else on the pitch, illustrating his heavy influence on the game.
He scored West Ham's second, with a precise finish after being found in space by the excellent Grady Diangana.
And he claimed his second goal to restore West Ham's lead, his low shot cannoning into the net via a deflection off a despairing Ben Mee.
He was also involved in his side's fourth, it was his sublime cross-field pass that began the attack which led to the goal.
"I am delighted for him because we know what he can give us," said Pellegrini of Anderson's performance.
Young Englishman Diangana also stood out. The 20-year-old winger was direct in his approach and he gave Clarets left-back Charlie Taylor a torrid afternoon.
He made five key passes, more than any of his team-mates, and provided the assist for the Hammers' second goal.
Burnley's struggles continue
After successive thumpings by Manchester City and Chelsea, Clarets boss Sean Dyche would have looked at this match as one his side needed to take points from.
But despite their resilience, which saw them equalise twice, they did not deserve anything from the game.
They were forced onto the back foot from the first whistle and struggled to gain any momentum at any point.
Dyche was animated over what he thought was a foul in the build-up to West Ham's second goal, but ultimately it proved inconsequential as the Brazilian stuck again before Hernandez added a fourth, consigning Burnley to their third defeat in a row.
They have conceded 13 goals in their past three league matches, and it could have been more against the Hammers with Mee and Hart both putting in impressive performances.
Man of the match - Felipe Anderson
'We could have scored more' - what they said
West Ham United boss Manuel Pellegrini: "We needed to win because we have had a lot of games where have created chances but not won. Yes, we could have scored more.
"The first and most important thing is we won the game. We have been playing well and creating chances but we have either drawn or lost. We trust the way we play. I think the fans enjoyed this and in the moments of bad results I have always felt they were behind the team."
Burnley boss Sean Dyche, speaking to Match of the Day: "We reacted well to falling behind. The mentality and energy were good in the first half. The third goal is a real blow and we are chasing the game when they score the last one.
"I'm not disappointed with the mentality of the team but we can't give away the ball so cheaply. There are some details in that game that need working on."
Hernandez scores from the bench again - the best of the stats
- Burnley have won just once in their last eight Premier League away games (D2 L5), losing four of the last five.
- The Clarets have failed to keep a clean sheet in nine of their last 10 Premier League games, shipping at least twice in six of those contests.
- Chris Wood has been directly involved in five goals in three Premier League games versus West Ham (four goals, one assist).
- Since the start of last season, Johann Berg Gudmundsson has been directly involved in 16 Premier League goals (four goals, 12 assists) - more than any other Burnley player.
- West Ham's Marko Arnautovic is now the highest goalscorer in all competitions at the London Stadium (nine goals).
- Only Jermain Defoe (24) and Olivier Giroud (19) have scored more goals as substitute in Premier League history than West Ham striker Javier Hernandez (17).
West Ham and Burnley both face away matches next Saturday. The Hammers travel to Huddersfield, while the Clarets face Leicester City at King Power Stadium (both 15:00 GMT kick-offs).
