Postecoglou said: "That's a harsh term, 'give up'. What does that mean?
"I come in here at 12 o'clock have a latte, go home and just let the guys train? I don't give up on anything. I'm here fighting tooth and nail every single day for everything I can get for this football club because that's my responsibility. I would not give up on any cause, even the most lost of causes because then I'd be abstaining from my responsibilities. I want us to finish the season strong. I want us to try and win three games of football and see where that takes us.
"I never said I didn't care about finishing top four. What I said was finishing top-four does not mean we're going to be the team I want us to be next year.
"That's not what will define us. I don't give up and I'd be surprised if anyone in my position at this level will go in with anything other than 100 per cent commitment to fight for everything because if you don't invariably you fail."
