BERLIN (AFP) - Bayern Munich has signed Germany defender Mats Hummels, his club Borussia Dortmund confirmed on Tuesday (May 10), while the Bavarian giants have announced the transfer of teenager Renato Sanches from Benfica.
Centre back Hummels is the third Dortmund star to join Bayern in the past few years after midfielder Mario Goetze in 2013, followed by striker Robert Lewandowski in 2014.
"For the coming 2016-17 season, the Borussia Dortmund player Mats Julian Hummels will transfer to FC Bayern Munich," said Dortmund in a terse statement.
"Both clubs have now reached an agreement in principle and the formal completion of the transfer, and the usual medical examination of the player, should be completed in the coming days."
Reports in the German media say Bayern have paid up to €38 million (S$59 million) for Hummels, who had a year left on his Dortmund contract.
The 27-year-old, who left Bayern in 2009 for Dortmund, is returning to Munich having won the German league title twice with Dortmund (2011 and 2012) and the German Cup (2012) before helping Germany win the 2014 World Cup in Brazil.
Bayern also announced on Tuesday the signing of Portugal international Sanches from Benfica on a five-year contract, having beaten Manchester United to sign the 18-year-old.
Bayern say they paid €35 million, plus possible bonuses, for the defensive midfielder, who won his first cap earlier this year. He made his debut for Benfica in the Portuguese league only last October.
