The former Swedish international told a website in his native country that he is getting frustrated at the lack of chances being given to him at The Hawthorns and will seek talks about his future if the situation remains the same after Christmas.
The 31-year old has started just nine times since joining the club in the summer of 2012 and has yet to score in 33 appearances.
He said: "The manager says that I will get the chance but I never get it. We have a big squad and he chooses other players.
"It is a tough time and it has been for almost one and a half years."
The striker was also disappointed to see new arrivals in his position during the transfer window.
He continued: "That felt tough. I played and scored in pre-season so I don't think I can do any more.
"I will wait until the transfer window in January and will see if I have got playing time by then. If nothing has happened, I will have to sit down and talk with the club."
But he denies that he is already seeking a move.
"I have not talked to any clubs," he told Fotbollskanalen.se. "But I want to play football. I have had patience all this time but now it is tough."
