The 27-year-old wanted to leave the club in the summer due to lack of playing opportunities, but he couldn't seal his exit from the club.
He is yet to make a league start for Slaven Bilic's side this season, but he came off the bench to score the last-gasp winner in the 1-0 win over Swansea on Saturday.
He said: "It's not easy to prove to the people what I can do on the pitch when I only play for 10 minutes.
"But I don't need to knock on the manager's door – he knows what I can do, now I have to force my way into the team. I just want to enjoy being part of this team and we will see what happens in January."
