Postecoglou later said: "We were outstanding in all facets. First half we made them work really hard. We maintained that tempo with our pressing, and the quality of our football in the second half was outstanding against a very good team.
"It was a big game with plenty of significance so for us to perform like that was a big credit to everyone.
"I felt towards the end of the first half they were working awfully hard to try and press us. That was the message at half-time that just perseverance would get us there today.
"We went on, we didn't stop playing our football. Great focus.
"I thought today, if we could impose our intensity and tempo on the game for 100 minutes we'd be hard to stop.
"It's not easy, especially away from home, but I though we handled ourselves really well.
"It means we're one game closer, just 11 games to go. Everyone was billing this as a do-or-die for us. I assume we're not dead yet."
