Kaboul was sent off in the 4-0 rout.
"When you look at the game, if someone watched the first half and didn't watch the rest, then saw the scoreline of 4-0, they would ask 'what happened?'" he told the Spurs website.
"The thing I'm upset about is that we fell apart after 2-0.
"I thought we started the game very well, the first half was good, we played some good football and could have scored with Nabil (Bentaleb) and Sandro.
"We started the second half well as well but then we made a mistake, okay, then the second goal. For me, it wasn't a penalty.
"After that, we fell apart really and it's not good enough for the club. We have to do much better than that, even if there are consequences in the game that go against us.
"We should have a better reaction."
