The Germany international has dismissed the suggestion that he is preparing to move to Camp Nou, while also claiming that BVB will cope with the loss of Robert Lewandowski
The Germany international is under contract to BVB until 2017 but has been repeatedly linked with a big-money switch to Camp Nou.
However, Hummels insists that the is going nowhere for now, arguing that his sole focus at the moment is on making a successful return from an ankle injury at the end of the month.
"I have been learning Spanish since seventh grade," the 25-year-old told Bild. "But I'm honestly not thinking about [Barcelona].
"My goal is to be back for the game against Eintracht Braunschweig [on January 31]. I want to have gone through a week of full training before my return, in order to find my rhythm."
Dortmund have struggled domestically in Hummels' absence and currently sit fourth, 12 points behind leaders Bayern Munich.
The Bavarians also recently announced that Robert Lewandowski will be moving from Signal Iduna Park to the Allianz Arena this summer - but Hummels sees no grounds for pessimism for BVB.
"Every year at least one player has left," the centre-half mused. "I already knew in 2012 about the fact that Robert would be leaving us.
"Plus, our bosses have always found excellent replacements and they will again this year."
Hummels also dismissed the suggestion that Dortmund are currently paying the price for failing to strengthen their squad adequately last summer.
"This is totally wrong," he countered. "If you are to compare us with Bayern, you should also take into account the financial resources of both clubs.
"Bayern have been outstanding but they have a few hundred million more than us to put together a squad.
"We have no debt and have also bought strong players. And, even though it might always sound like an excuse, [Dortmund's struggles] are clearly due to the many injuries we have had. Almost all of those injured were leaders with a lot of influence on our game."
