Despite the significance of the upcoming match, Postecoglou insisted he does not feel additional pressure and remains confident in his team’s ability to turn things around.
"No, no extra pressure," he asserted. "We were obviously disappointed with our performance in the first leg. The important thing is we didn't make the tie impossible for us to get back into, it's still very tight.
"They've got the goal advantage but playing at home, if we can play with the intensity and tempo that we did in the weekend [2-2 comeback draw with Bournemouth] then I think we will have an opportunity to progress. Should we progress, we will have another big challenge in the next round. The focus is to put in a strong performance tomorrow night."
