BORUSSIA DORTMUND coach Nuri Sahin lashed out at reporters in a tense post-match TV interview.
The former Liverpool midfielder saw his BVB side beat St Pauli 2-1 on Friday night.
Sahin took over at the Bundesliga club over the summer after Edin Terzic’s departure.
Dortmund have made a mixed start to the new campaign, losing two of their opening seven league games.
Sahin’s side needed a late Serhou Guirassy winner to see off newly-promoted St Pauli at Signal Iduna Park.
And he didn’t mince his words after being confronted by DAZN over his team’s “mentality.”
Sahin, 36, fired back: “This team does not have a mentality problem.
“Playing at the level of Borussia Dortmund, you cannot have a bad mentality.
“I will not allow people to talk about my team like that, for God’s sake.”
Despite defending his players, Sahin did call out their lax work off the ball in the narrow win.

Pauli midfielder Eric Smith stunned the hosts with a late leveller and had earlier had a goal ruled out for offside.
Adam Dzwigala was given acres of space late in the contest to almost snatch an unlikely point.
Sahin continued: “The way we defend really annoys me.
“Scenes like [the Dzwigala chance] make the difference between whether we have 11 or 13 points here.
“We’ve already conceded goals like that against Celtic and Union. That’s not acceptable.”
During his playing days, Sahin made 274 appearances for BVB, winning both the Bundesliga and the German Cup.
He also enjoyed time at Real Madrid and Liverpool throughout his career.
Sahin made 12 appearances for the Reds in the 2012-13 season when he signed on a six-month loan deal.
