Kieron Dyer hit back at criticswho whine about his lack of contribution to West Ham after making his first appearance at Upton Park for three months.
The club's co-owner David Sullivan has even said that a player earning £60,000-£70,000 a week who does not play much 'might have to accept retirement'.
Defiant Dyer, who earns £70,000 a week, will refuse to give up on his career, though.
Fingers crossed: Kieron Dyer
The former England midfielder,who recently recovered from a hamstring injury, came on shortly after half-time and gave a surprisingly lively display.
Dyer defended himself bysaying: 'Everyone has forgottenthat I had probably a worse leg break than Aaron Ramsey and have had four operations to try to get it right.
'I have put in everything I can to get fit for this club. But it is not enough for some people. All I can do is get my head down.
'I have the backing of the manager and hopefully I can get there. Hopefully I can change some other people's minds.'

Regarding recent comments from the board, Dyer said: 'If you buy a football club and you are the owners, you say what you want. They are entitled to their opinions.'
Hammers fans view injury-prone Dyer as a symbol of the club's wasteful spending.
The statistics prove them right.His rare run-out on Saturday took his total league game time at West Ham above 600 minutes.
Sadly, it's taken him more than two and a half years to get there. Most first-team players take less than two months to clock up that many minutes.
Dyer, 31, has cost the club about £400,000 a match since he joined from Newcastle.
West Ham will have spent £30million on him by the end of hisfour-year contract.This was a difficult home game for Dyer to return on.
'Even though I came on for 45 minutes, it was a very disappointingday,' admitted Dyer.
'We usually start off like a house on fire, get out of the traps and get in people's faces.'
It was Bolton who did that on Saturday, though, as West Ham's disjointed defence were given a torrid time by Owen Coyle's attack-minded wingers and busy front pairing.
Bolton led in the 10th minute when Gretar Steinsson supplied Chung-Yong Lee, who crossed into the six-yard box.
Breakthrough: Kevin Davies notches the opener
The outstandingKevin Davies got between Julien Faubert and James Tomkins to head in.
Tomkins was out-thought by Davies for Bolton's second, eight minutes later.

He imaginedhe could let Steinsson's long ball run out of play. Davies, however, got round him and hooked the ball into the penalty area where Tamir Cohen's cushioned header allowed Jack Wilshere to score - but it was Davies who deserved the credit.
'The first half was unbelievable,'said Davies.
'We have won six in a row against them. We knew what their strengths were and that was going forward and we knew that we could have a go at them defensively.'
Cohen's second yellow card in the 70th minute gave West Ham hope. The home side's only creative spark in midfield Alessandro Diamanti scored with a curling 16-yard effort with two minutes to go.
This led to a frantic finish. First Davies for Bolton, then Junior Stanislas for West Ham, hit the bar.
But the visitors were worthy winners, with a discontentedhome crowd frequently showing their displeasure.
