Koren has been linked with Celtic, Fulham, Birmingham, Tottenham and Wigan this summer.
“The transfer window is not closed yet,” he said.
“There are still some days remaining, but I must admit that I’m very happy at West Brom.
“I have a contract, I’m respected here and it would be very hard to leave.
“Of course, if an offer came in that suited both me and the club then I could leave, but I’m happy at West Brom and would have no problems staying.”
