Nuno Espirito Santo accepted responsibility for Tottenham's 3-1 loss to Arsenal in the north London derby, saying he "did not make the right decisions."
Tottenham had no answers for their opponents, who were boosted by academy graduates Emile Smith Rowe and Bukayo Saka, who both scored and assisted in a convincing win.
Gunners striker Pierre-Emerick Aubameyang also scored as Arsenal went three goals up at the break, but Son Heung-min pulled one back for a Spurs team that had struggled for ideas for much of the game.
Nuno's aptitude for the post of Tottenham manager has already been questioned just 88 days after he took over — Spurs have now conceded three goals in three Premier League games for the first time in 18 years.
They were top of the league heading into the international break, and their fans were ecstatic to see Arsenal keep the table afloat.
Arsenal, on the other hand, rises above their local rivals thanks to this resounding victory, as they continue to rebound from a terrible start to the season.
Nuno also admitted that he was to blame for Tottenham's defeat.
“A lot of things went wrong, starting with decisions that I made,” he said.
“It’s not easy to expand, so I just ask for a bit of respect if I don’t go too much into it.
“The game plan didn’t work out. I’m very honest. If the game plan didn’t work out the way you wanted it to work out, it’s because you didn’t decide it well.
“I decided badly. Didn’t make the right decisions. And I refuse to go much further than that.
“It’s my responsibility. All I have to say, I’ll say it to the players among us. Because us (we) must solve the problem.”
Spurs improved after the break, which was not a difficult challenge, but Nuno acknowledges that it was too little, too late.
“We’ve been in football too long to realize that the positives from a second half in this game are almost lost,” he added.
“This thought that if we achieve a goal early in the second half maybe we then can react and go for it. It didn’t happen, but all the positives are very fragile in terms of analysis that we should do.”
