The Australian striker has just over a year to run on his current Boro deal but will ponder his options at the end of the current Championship campaign with the Riverside Stadium outfit set to miss out on a promotion playoff position.
"Everyone will ask if I will still be here, " McDonald told the Northern Echo.
"People will talk, people can say what they want. I am not interested in what anyone says.
"Me, the manager and the club will have a chat and we will take it from there. We will then see what the situation is for every party and what's best for everyone."
With 11 league goals this season McDonald has come under scrutiny for being a highly-paid player at Middlesbrough but he insists he is in no hurry to depart in order to ease the Teessiders' wage bill.
"Of course I want to get to the Premier League, but I'm in no rush to get away," said the club's leading scorer.
"That's not me saying I want to get away. Maybe some people would like me to go away!
"Unfairly for me, I have been highlighted a lot. In all due respect, the club has a high wage bill and it is not one individual that makes up a high wage bill. That's fair enough.
"I will keep working hard and doing my best for the football club which pays my wages. That's all I can do. If I can come off the pitch and know I have given everything then I will be happy."
