#4 Rafinha
The Brazilian footballer, who started his Bundesliga career at FC Schalke, moved to Bayern Munich in the summer of 2011. He has been a reliable player and has always performed whenever called upon. However, he has failed to hold up a regular starting position in the team and his role has often been reduced to being just a squad player.
Rafinha extended his contract for one more season last year. It was a blessing in disguise for Bayern as Rafinha often filled in for injury-prone David Alaba as a left back and also played at the right back position when Joshua Kimmich needed a rest. He is good in defense and also is a good crosser of the ball.
Bayern may not extend his contract again this season as they will be hoping to sign younger talent in order to provide competition for both Alaba and Kimmich.
