The 25-year-old Sweden international's scintillating goalscoring form - he has 22 to his name so far this season - has seen him repeatedly linked with a move away from St James' Park with Arsenal among the destinations persistently touted.
"I think we should really look at it one season at a time and this season we can achieve winning a trophy which would be amazing for everyone.
"About my future, it's nothing really I think about
I've said many times during a season just focus on the job and now is probably the worst time to think about anything else so all of our focus is just on Sunday and doing good and hopefully bringing the trophy back to Newcastle."
Asked if he was open to signing a new deal at St James' Park this summer, he added: "I've said I'm not really thinking about the summer, but yes, that'll probably be a talking point once the season is finished.
"We will really see because no talks have been held yet."
