Manchester City boss Manuel Pellegrini is unsure how Frank Lampard will react if he scores at Chelsea today.
But he promised to celebrate for the both of them should the veteran midfielder bag against his former club yet again.
"First I prefer him to score the goal," Pellegrini said when asked about the prospect of Lampard repeating his feat from the sides' meeting in September.
"After that we will see if he celebrates or if he doesn't celebrate. If he scores, I celebrate!"
