The 24-year-old is one of the hottest prospects in world football and has attracted the reported interest of both the Premier League and Liga champions.
It is likely that Dortmund would not even listen to bids under €50m for the attacking midfielder, although a €35m release clause will trigger into effect in Reus' contract in the summer of 2015.
"I have a valid contract with BVB and am happy to be here," Reus told Bild when asked if he would still be at Dortmund by the end of 2014.
"To be honest, I've read very little about interest (from United and Barcelona) and if I do hear of interest from time to time, I consider it an achievement."
When asked by the German paper if he could see himself triggering his release clause in the future like his former team-mate Mario Gotze who moved from Dortmund to rivals Bayern Munich, Reus said: "I can only say I do not think about it all. Anything other than Dortmund at this time is very far from my mind."
