Spurs meet Saints this weekend for the first time since Pochettino's departure.
"I don't know [if the fans love me]," he said. "I love Southampton. I love a lot of people.
"That year-and-a-half in my life was an amazing period and I left, but this is another thing. I have amazing memories from Southampton.
"I know it's football. Now I am happy that they are happy at the beginning of the season and for me that is enough.
"In football, you deserve, you don't deserve [certain things]. Some people say okay, some people say no, but this is football.
"I'm happy Southampton have a great season and it's a game that we need to win the three points.
"We need to fight with Southampton on Sunday, but it's emotional. Football is emotional and Sunday is emotional for us too."
