The Brazilian's European bow for the German champions pleased his coach on a night that Thomas Muller made history
Bayern Munich coach Niko Kovac believes Philippe Coutinho has brought "another dimension" to the team after he impressed in their Champions League win over Red Star Belgrade.
"He played a really good game and with his football intelligence he brings another dimension to our game," Kovac told Sky in Germany.
"I think we can be very happy. The team has been very focused and we scored three goals, that's befitting."
Muller came off the bench to make a club record 106th appearance in the Champions League for Bayern, but he played down its significance.
Muller said: "Such game records are something for after the career, and I'm not going to give up my shoes up in the near future, so it's not that important."
