Philippe Coutinho "only counts as half a player" for Bayern Munich at the moment, according to Dietmar Hamann, who feels the attacker is not contributing enough going forward or in defence for his new club.
The Brazil international joined Bayern on a season-long deal from Barcelona in August, after being deemed surplus to requirements for the 2019-20 season by Camp Nou boss Ernesto Valverde.
Much was expected of Coutinho when he completed a £142 million ($182m) switch to Barca from Liverpool in January 2018, but he has struggled to stand out in a side full of world-class talent.
