Andy Carroll felt West Ham gave the perfect response to Dimitri Payet's walkout by thumping Crystal Palace without him.
Midfield star Payet refused to play against the Eagles on Saturday after telling manager Slaven Bilic he wants to leave the club.
But the Hammers showed there is life after the France international with a 3-0 win and easily their best performance of the season.
Carroll scored what he admitted was the best goal of his career, a stunning bicycle kick, in between strikes from Sofiane Feghouli and Manuel Lanzini.
The striker said:
I think we have answered a few of the critics, 100 per cent.
With everything that has been going on during the week and everyone talking it's been tough, especially as the lads are close to one another.
To put all that behind us and work as a team has been fantastic. The fans were like the 12th man and were great with their support. It was a great day all round. All the lads were fantastic and professional. They know what it means to the fans and the club.
We stuck together and everyone is hungry and dedicated - and it showed in the performance.

West Ham joint-chairman David Sullivan has vowed not to let Dimitri Payet leave this month.
France star Payet this week rocked the Hammers by telling them he wants to quit the club and has refused to play against Crystal Palace on Saturday afternoon.
The 29-year-old, who signed a bumper £125,000-a-week five-year contract last February, is understood to want a move back to former club Marseille.
But Sullivan appears to be digging his heels in.
Writing in his programme notes ahead of the Palace match, he said: "The board's position is that we do not want to sell Dimitri, we do not need to sell Dimitri for financial or any other reasons, and we will NOT sell Dimitri in the January transfer window.
"All we ask now is that he shows the same level of commitment to West Ham United as the club and the fans have shown to him by honouring his contract."
Hull City have rejected a £3million from West Ham for Scotland international Robert Snodgrass.
The forward has recently been linked with a move to Celtic, but the Tigers triggered a contract extension until the summer of 2018.

Joe Cole has tipped his old club West Ham to play Champions League football at the London Stadium in the future.
The Hammers have struggled to adapt to their new surroundings since making the move from Upton Park at the end of last season.
But Cole, who made 187 appearances over two spells with West Ham, scoring 18 goals, is convinced the switch to the former Olympic Stadium will eventually pay dividends.
I think it is an amazing stadium and it looks immense. I was getting an itch just looking out at the pitch and would love to have been out there playing.
When you come to a new stadium you are going to have some little problems, but this is forward thinking by West Ham and is 100 per cent the right thing to do. With a few more good results I am sure it will begin to feel like home.
It was amazing for me to play at Upton Park, and it was special in its own right. But time waits for no-one and West Ham have now got the capabilities to compete with the biggest teams in the world.
It is exciting times for the club and West Ham can now compete with the top teams financially.
You can see Champions League football being played at London Stadium. If you are honest, you probably couldn't see that happening at Upton Park.
West Ham have told the Football Association they will appeal against the red card shown to Sofiane Feghouli during Monday's defeat to Manchester United.
Feghouli was sent off after 15 minutes by referee Mike Dean for a tackle on United defender Phil Jones as the Hammers lost 2-0 at the London Stadium.
Replays suggested the decision had been harsh and West Ham will now appeal in the hope of sparing their midfielder a three-match suspension.
A club spokesman told Press Association Sport: "The FA have been informed of our intention to appeal."
If a three-match ban is upheld, Feghouli would miss West Ham's FA Cup third round tie at home to Manchester City on Friday, as well as Premier League fixtures against Crystal Palace and Middlesbrough.
Feghouli was making his first league start of the season against United after joining Slaven Bilic's side on a free transfer from Valencia last summer.
