Ange Postecoglou said he was not "hurting" but "determined" to turn Tottenham's fortunes around after their inconsistent season continued at Bournemouth on Thursday.
Postecoglou watched on as his side slipped to a 1-0 defeat to the Cherries at the Vitality Stadium, with Dean Huijsen's first-half header sealing the victory for the hosts.
The result saw Tottenham slip to 10th in the Premier League, having won just one of their last six games in all competitions, with that victory coming against Manchester City.
Following the full-time whistle, several Tottenham fans confronted Postecoglou as he made his way over to the away end, with the Australian engaging in conversation.
This Sunday, London rivals Chelsea are the visitors to the Tottenham Hotspur Stadium, and Postecoglou is aiming to put things right on home soil.
"I'm not hurting, I'm determined, that's all. I don't want to say it's unacceptable (the fans' abuse) because it is what it is," Postecoglou told reporters.
"I've lived in this world for long enough to know that when people aren't happy they'll express their opinions, and I'm never going to hide, I'm never going to shirk that responsibility. I'll take (it) on board.
"Is it nice? No, because like I said last night, I'm not just a manager, I'm a human being like everyone else. None of us like to hear those sorts of things, but it is what it is.
"It doesn't disappoint me, it doesn't frustrate me, it doesn't make me angry; I'm just as determined as ever to get it right. Not because of that, but because of my resolve to bring success to the football club."
Postecoglou said he was still searching for answers to Spurs’ inconsistency, and is also hoping to improve his own record in London derbies.
After winning his first four games in charge of Tottenham against teams across the capital (W2 D2), Postecoglou has now lost seven of his last 13 such matches (W4 D2).
Adding to his woes was an injury to Ben Davies, who was playing as centre back in the absence of injured duo Cristian Romero and Micky van de Ven.
“Ben will go for a scan today so we’ll find out more," Postecoglou said. “Cuti’s (Romero) due to training, but we’ll see how he goes on Saturday."
“Chelsea are going really well, they are in a good space at the moment with a fairly healthy squad and in good form.
"Always a tough game against them but we are at home, and we need to make sure we produce a performance like we have in the other games," he added.
