Liverpool face tough test at boyhood fan Postecoglou's Spurs
Postecoglou's attacking style has won plenty of admirers since he joined Spurs in July and the clash between two of the league's four unbeaten sides could be a lively affair.
Fourth-placed Tottenham are enjoying their best start to a league season in 57 years while Liverpool in second are chasing a sixth successive league win and eighth in all competitions.
Postecoglou's football journey was inspired by the great Liverpool sides of the past so the clash will be a trip down memory lane and can make a big statement about his side's future.
"I was a massive Liverpool fan. I loved Bill Shankly, I loved the boot room, the whole story," he told former Spurs and England striker Gary Lineker in a recent BBC interview.
"I've taken the posters down, mate. Last week," he joked, when asked if he was still a fan.
Tottenham, who have won only once against Liverpool in their last 20 league encounters, are hoping their England playmaker James Maddison will be fit for the evening game after jolting his knee in the 2-2 draw at Arsenal last weekend.
Liverpool have scored three goals in each of their last five matches and rested key players in the 3-1 League Cup third round win against second-tier Leicester City at Anfield on Tuesday.
