Middlesbrough star Scott McDonald insists he is committed to helping the club back into the Premier League.
The Australian was quoted over the weekend admitting he would be tempted by a move back to former club Celtic.
But McDonald, who has bagged four goals since his £3.5million switch in January, insists that he is firmly focused on Boro - although his main aim now is to win a place in Australia's World Cup squad.
"It hasn't even entered my head that I could leave this summer," said the Australian.
"All I am concentrating on now is the World Cup. Then I will get back here and settle in again for the start of the new season.
"Moving here and there and moving on to a new club is not something you want to keep doing.
"At the moment it's playing for Middlesbrough that I want. I want to be successful here and push this club back up.
"I love working with the manager. The main reason I came here was to work with him and Garry Pendry, his assistant, again. He trusts me and that gives you extra confidence as a player and I enjoy it. It gives you lee-way to express yourself."
McDonald could be one of three Boro players in the Australia squad, with Brad Jones and Rhys Williams also hoping to make the plane to South Africa.
"It would be great for the club to have three boys representing the one nation," he said.
"I don't know what the script will be for Rhys, there's a bit of a worry there. But hopefully he can now rest up and find full fitness."
Williams is struggling with his ongoing pelvic problems, saying: "It feels like its going to snap every time I run.
"I'm not really training and I'm getting through games with injections, it's not ideal but I'm getting through it.
"Maybe in the summer I'll get it fixed, if there's time, I'll do what I need to do to be fit next season."
