Middlesbrough striker Mark Viduka admits he has yet to decide whether he will commit his future to the club.

The Australia international, 31, is out of contract at the Riverside and is thought to be coveted by a handful of clubs, including Newcastle and Portsmouth, after hitting 19 goals this season.

He said: "We will see what happens in the next few days, but it has been one of the hardest decisions I have ever had to make and I haven´t come down on one side or the other yet."
