With the Sweden international having started just two league games this season, the Baggies boss has confirmed he will sit down with the striker to discuss his current situation
The Sweden international has made just two league starts since moving from Werder Bremen last summer, with the form of Shane Long and Romelu Lukaku regularly keeping him out of the side.
And Clarke has confirmed that he will speak to the 30-year-old about his current situation and try to decide an outcome that will satisfy both him and the club.
"It's been a frustrating season for Markus. He's never really been given the chance to show his potential mainly down to the form of the other players," Clarke told reporters.
"I'm aware Markus is really disappointed, and a little bit down. He comes to speak to me quite often. I respect him for that. He lets me know his frustrations face to face.
"Does he stay beyond this season? That is not a discussion we've had yet. I'm sure between now and next season we have to sit down and discuss things because he is not a young man anymore.
"He is not the type of person who is happy to sit on the bench and just pick up his money. I'm sure it's a conversation we will have.
"We will sit down and decide what is the best thing for Markus and West Brom."
