Stuttgart's director of sport Fredi Bobic has warned his side Georg Niedermeier not to complain if he does not start tomorrow's game at Werder Bremen.
Speaking after Thursday's 2-2 draw with Steaua Bucharest in the Europa League, the German defender let his frustration get the better of him when he spoke of his disappointment at not being able to command a regular starting berth in the side this season.
However, Bobic says he has got to learn to accept that, especially with so many games in such a short period of time, nobody is guaranteed a starting place.
``We want people who speak their minds, but one or two people have got to make sure they don't overrate themselves,'' said Bobic at a press conference.
``A professional footballer must know where the boundaries are.
``Borussia Monchengladbach left three players behind when they played in the Europa League, but this moaning from players who maybe don't play a game now or then does not exist anymore.
``It is unacceptable.''
Niedermeier may find himself on the bench again tomorrow, and he should accept the coach's decision.
``He lost the battle with Maza and Serdar Tasci in pre-season,'' commented Stuttgart's coach Bruno Labbadia, who should again be able to rely on the latter against Bremen.
He cannot count on Vedad Ibisevic, though, as the Bosnian sits out the second of a two-game suspension tomorrow.
Bremen coach Thomas Schaaf has also expressed his frustration - that his side do not have more points on the board.
A 3-2 defeat last weekend to Hannover has left them with just three points so far this season.
``A win would do us good,'' said Schaaf. ``We want more points.
``The team is frustrated that they don't have more than they do, especially in view of our recent performances.''
