The 25-year old midfielder has spent the past month with the Cherries but will return to east London and attempt to force his way into the Hammers first team.
"I will be looking to play in the League Cup tie (against Burnley on Tuesday) and then see where I am after that. I would like to force my way into the West Ham team but if it's not to be, it's not to be," he told the Daily Echo.
"I have had a fantastic time here and would definitely be open to coming back and trying to improve on what I did. The philosophy of the management team and the way the team plays suits me.
"The training has been magnificent and you can see from the effort and enthusiasm they put that this club is only going one way."
