Bayern Munich have confirmed that they are in talks with Borussia Dortmund over the signing of Mats Hummels.
Hummels has been heavily linked with a move away from Dortmund at the end of this season, with the likes of Manchester United also understood to be interested in the defender.
However, the 27-year-old now looks set to follow in the footsteps of Mario Gotze and Robert Lewandowski in making the switch from Dortmund to Munich.
"I can pretty much confirm... that Mats is talking to Bayern," Bayern chairman Karl-Heinz Rummenigge told reporters.
"But these are talks between three parties and please understand that I cannot go into more detail at this moment.
"We have to respect that he is under contract at the moment [until 2017] and I don't want to ruin the good relationship we have built up [with Dortmund] with some comments today."
Reports have suggested that Hummels, who began his career with Bayern, could be involved in a swap deal that will also see Gotze return to his former club.
