It is no secret the German stopper is one of the first names on the list to replace captain Carles Puyol at the end of the campaign.
And while Hummels is unlikely to come on the cheap, the Catalans will be encouraged by the fact the player is reportedly keen on moving to Camp Nou.
El Mundo Deportivo understands the 25-year-old is looking for a new challenge after enjoying a great deal of success with Borussia Dortmund, and he has reportedly informed his close friends of his desire to join Barcelona.
Mats Hummels has spent last six years at Signal-Iduna Park, making a total of 161 Bundesliga appearances and scoring 14 goals in the process.
He has won two Bundesliga titles with the Millionaires, DFB Pokal, Liga Pokal and German Super Cup trophies.
