Ange Postecoglou should be a happy man after watching his Tottenham Hotspur side beat Bodo/Glimt 2-0 and 5-1 on aggregate to cruise into the final of the Europa League on Thursday.
But the Australian was far from happy with one question in his post-match press conference.
Postecoglou has made a habit in this most dismal of seasons domestically of hitting back at questions from reporters that he did not like as the pressure has been heaped on his shoulders.
He has also had a number of altercations, caught on camera, with supporters after poor performances.
Everything should be happy from a Tottenham persuasion given their triumph and qualification for the Europa League final in two weeks' time.
But Postecoglou was in a less than smiley mood when asked what it would mean for Spurs to win the Europa League. That was because the question referred to Manchester United - their opponents in the final - and what it would mean for them.
The question came: "United have said winning this wouldn't save their season, would this save Tottenham's season, is it different for Tottenham?"
Postecoglou hit out, somewhat unnecessarily, immediately.
"I don't care, why do I care what Man Utd think?" he roared. "Why is that relevant to me? Me, I've said all along that this is important. the question answers itself, it doesn't need me to answer it."
In the TNT Sports studio, David Bentley could not quite believe what he had heard and sent a simple message to the Spurs boss.
He said: "He should focus on the positives and not react to it. In recent weeks he's been responding and he should just go quiet, focus on the positives.
"He's got into a little argument here and he's been doing that a lot more which is having a negative reflection on himself."
