Southampton manager Ronald Koeman came to the defence of Mauricio Pochettino after his squad lost 1-0 to Tottenham.
Saints' fans chanted at their former boss Pochettino, who now patrols Spurs sidelines.
"Yes, okay that is the reaction of the fans and I don't agree with that," the Dutchman said. "I think everybody needs respect and normally the respect is high in the Premier League.
"I respect Mauricio very much and he did a great job in Southampton. Now he is the manager of Tottenham and it is a great challenge for him."
This was a timely shot in the arm for Pochettino's side ahead of the international break, although it could have so easily have been a draw.
Sadio Mane had Southampton's best chance but was guilty of a miss-of-the-season contender, turning wide from six yards out in the closing stages.
Younes Kaboul was perhaps fortunate not to be sent off after being adjudged to have brought down the winger earlier in the second half when the last man.
Koeman was coy when asked whether the Spurs captain should have been sent off and was pleased with his side's display in north London.
"I am disappointed about the final result, not disappointed about our performance," the Dutchman said.
"We knew it was difficult because in the first half they did great pressing. It was easy to create possibilities, opportunities.
"It was a pity because they scored before halftime and we spoke then about keeping good organisation in the second half.
"Little by little we had to push up a little bit more and I think we did that very good. We got maybe the best chance in the game with Mane. Okay, it was unlucky but that is football."
