Raphael Guerreiro confirmed to join Bayern Munich from Borussia Dortmund on a free transfer.

The 34-time German champions Bayern Munich officially confirmed the signing of Portugal left-back Raphael Guerreiro on a free transfer from Bundesliga rival Borussia Dortmund.

Guerreiro joins on a three-year deal after his Dortmund contract expires at the end of the month.

He will likely compete for the starting left-back spot with Alphonso Davies but he can also play on the left of midfield and was also used as a central midfielder by Dortmund this season with some success.

A Euro 2016 winner with Portugal, Guerreiro will reunite at Bayern with manager Thomas Tuchel, who brought the defender to Dortmund when he managed the club.

Guerreiro can also be deployed in midfield, where he was a major creative presence at the latter end of the season for Dortmund.

Guerreiro put in a league-high 12 assists this season, in addition to four goals.

"Raphael Guerreiro has been one of the best and most consistent players in the Bundesliga for years," said Bayern CEO Jan-Christian Dreesen.

Several players have made the move from Dortmund to Bayern over the past decade, including Robert Lewandowski and Mario Goetze.

Defender Mats Hummels was the most recent player to make the move, doing so in 2016, before returning to Dortmund in 2019.

Guerreiro is Bayern's second signing this summer after midfielder Konrad Laimer from RB Leipzig, who also arrived on a free transfer.
