The 25-year old striker was the subject of a £4.5million proposal from the newly-promoted Tigers but Hoops boss Neil Lennon says the Scottish champions are determined to retain his services this summer.
"We had a bid from Hull City which we rejected," Lennon told Sky Sports. "Whether they come again, I don't know. As you were.
"No set price. The offer made was well below our valuation of player. We would be very happy for him to stay and if he decides to stay on, contract negotiations may re-open again.
"He will come to Germany on Monday and will be part of our plans for [Champions League] qualifiers."
