Former Newcastle United and Middlesbrough striker Mark Viduka hasn't ruled out playing in Australia's A-League competition next season.

The ex-Celtic star has held talks with new franchise Melbourne Heart and has left the door open to a playing return.

''The A-League, compared to what we went through [as juniors], is unbelievable,'' Viduka told Fox Sports last night. ''People are so into it and it's a credit to Mr [Frank] Lowy and whoever set it up. Whether I'm going to play in it or not, I don't know. I'll have to see whether or not my body can take it.''

''I'm still in two minds. I'm a Libran so I have to balance things out. I'm thinking about it. It takes time.''
