Former Tottenham boss Mauricio Pochettino admits he is emotionally attached to the club.
The Argentine is set to play his old team with his new Chelsea side on Monday in the Premier League.
While Pochettino will always wish Spurs success, he hopes to get one over the league leaders this time around.
He told reporters pre-game: I want to win - I want to beat them. When I play with my kids I want to beat them of course, or my dad or my brothers or my friends - I try to kill them."
I hope we can arrive on the same level that I had at Tottenham because then it would mean we are doing really well here," Pochettino added.
We don't need to show something special, we need to be natural, that is the most important, not to be fake," he went on to say.
I don't want to be a hypocrite and say something that I don't feel or are in the process of creating. We cannot underestimate the Chelsea and Tottenham fans. The Chelsea fans know we were at Tottenham and the situation in the Champions League or the Battle of the Bridge.
Are we going to hide this emotion? No, it's impossible. And now I cannot say I forget all the things [at Tottenham] - that would be stupid. I'm going to be natural and show every game that I want to win."
