Jarvis, who signed from Wolves for a club record £10.75 million during the summer, has had a stuttering start to life in London.
The England winger, whose only current cap came in a 1-1 draw in a friendly against Ghana, has made just three league appearances for the Hammers, two of which have been from the bench.
Despite his transfer fee Jarvis has found it difficult to adapt at West Ham so far this season and assistant manager Neil McDonald says the players have to earn their place on the pitch.
McDonald told the Daily Mail: “Sam Allardyce has always believed that if you play well you stay in the team. Whoever can’t get in the team, and it might be a record signing, they have to wait for their chance.”
|5/1||West Ham are 5-1 to draw 1-1 with QPR with bet365|
West Ham face QPR in the Premier League at Loftus Road on Monday night, as they look to pick up their first away win in the league since February 2011.
The Hammers, currently mid-table, have had a promising start to the season - taking eight points from their opening five games - and McDonald believes the confidence from an impressive season in the Championship has aided their preparation for the return to England's top flight.
He added: “We had a formidable record in the Championship last season and we’ve got to try to take that on.”
