The 29-year-old will run out of contract with Hamburg at the end of the season, and Boro have reportedly shown interest in his services.
However, agent Gordon Stipic denied any contact with the Teessiders, as he stressed that his client has higher ambitions.
"We learnt about that [Boro's interest] from the press," Stipic told Sky Sports.
"But I have not had talks with them and to be honest we are not sure they would be worthwhile. I don't think they are the type of club that Ivica would consider at this stage.
"Of course a move to the Premier League would appeal, but any club at least would have to be in Europe and ideally in the Champions League - that is where Ivica wants to be."

Stipic revealed a number of top clubs, in addition to Hamburg, who are in talks with the Croat ace over a possible move in the near future.
"We are talking with Juventus, Valencia, Bayern Munich and of course Hamburg, and it would be very hard for us to talk to anyone else as we are a long way down the line with these clubs," he said.
"Time is pressing now and we will be talking again in Hamburg this week as we want to make a decision between now and the New Year.
"Ivica now feels he will be playing for one of the clubs I have mentioned."
