The Bayern Munich midfielder has long been linked with the Old Trafford club, especially as his contract situation with the German champions remains unresolved.
Kroos, 24, has a year left with Bayern and has yet to accept their offer of an extension, giving a nod to a possible move away.
United have been reported as suitors but he claims they are not on his radar.
Speaking to Bild he said: "I am expecting to play for Bayern Munich next season.
"There was a lot of speculation, but Manchester is and was not an issue.
"At this point in time I am fully focused on preparations for the 2014 FIFA World Cup."
Rumours of a United move for Kroos started to circulate when David Moyes was in charge, although talk has cooled since the appointment of Louis van Gaal.
