The 24-year-old’s agent, Per Jonsson, has revealed that several clubs are interested in signing the Sweden international.
Jonsson told Expressen: “I don’t want to comment on that.
“We’ll see. Right now, he is focusing on Birmingham.
“You could say there is interest from other clubs, but the thing with ‘interest’ is that it is not always completely accurate.
“Interest in my eyes has to be a piece of paper on the table that states, ‘We want him’.”
He added: “We are going to have a meeting and work out how we are going to go forwards.”
