Robbie Keane maintains he has "nothing to lose" as the Republic of Ireland striker looks to fire West Ham out of the relegation zone - starting at Blackpool on Wednesday night.
Along with fellow January arrivals Wayne Bridge, Gary O'Neil and fellow forward Demba Ba, the 30-year-old is expected to be thrown straight into the action by Avram Grant as his men battle for Barclays Premier League survival.
"It is something I am fairly used to now, coming to a new club," Keane said. "It is an opportunity for me, and I don't really have anything to lose. West Ham are bottom, all we can do is push up the table and I am here to hopefully do that to avoid relegation."
Grant believes Keane is just the character the Hammers need in their fight against relegation.
"I can only be myself, if other people can see me bringing something else to the dressing room, well great," the striker said.
"I am here to help the team, if that is off the pitch also with the character I am, then that is great.
"The spirit is fine here, there are good lads and top quality players."
Keane added: "Even before I came to West Ham, I thought they had the quality to stay up.
"Sometimes you find yourselves in situations where you are down there and it is very difficult to get out.
"It is important that sooner rather than later they get out of that situation they are in, and hopefully I can help them do it."
