Wolfsburg's Bas Dost needs to improve his attitude in order to play against Bayern Munich on Tuesday despite a match-winning performance against Hertha Berlin, according to his coach Dieter Hecking.

Dost came off the bench to score twice against Hertha but has been reprimanded by Hecking for sulking in training before Saturday's 2-0 Bundesliga victory.

"I'm pleased for the team that he scored two goals, but the way he has walked around for the last three days, as if someone had taken away his toys, will not do," fumed Hecking when asked about Dost's goals.

"That's being selfish and we don't need that.

"If he thinks that is the way he wants to go, then perhaps he is in the wrong place here in Wolfsburg."

Dutch striker Dost came off the bench for former Arsenal forward Nicklas Bendtner against Hertha on 71 minutes, giving Wolfsburg the lead just five minutes later before netting a penalty shortly before the final whistle.

But Hecking was far from impressed when Dost reacted badly to being substituted for Bendtner early in the second half of their 1-0 Champions League win over CSKA Moscow last Tuesday.

As punishment, Dost started against Hertha on the bench, despite scoring 16 goals in 21 league games last season.

Hecking has no intention of smoothing things over with Dost, despite the looming trip to champions Bayern, who have won five out of five in the Bundesliga this season.

"I'll let him have three days now in silence -- just as he has done with the team," said Hecking, who coached Wolfsburg to second in the Bundesliga last season before winning the German Cup.
