Zarate, who has scored two goals this season, has struggled to secure a place in Sam Allardyce’s side after falling down the pecking order behind Andy Carroll, Diafra Sakho and Carlton Cole.
The 27-year-old, who joined the Hammers from Argentine side Velez Sarsfield in the summer,??has played just eight times this season and will join up with Harry Redknapp’s side in a bid??to get more first team football.??
“I respect the other strikers at the club who have done a good job,” Zarate was quoted as saying the national press.
“But I believe my record entitles me to respect and I have not had that from the manager. The chairman has confidence in me. I know this because he brought me to the club.
“But for this reason the manager has refused to play me. He did not want me. I made it clear many weeks ago that I wanted to leave.”
QPR have also been linked with former Tottenham duo Jermaine Defoe and Robbie Keane but Redknapp has played down the rumours.
