Lampard almost left Chelsea for Inter Milan
Lampard opted to stay with Chelsea, who face Inter Milan in the Champions League on Wednesday night, but has now conceded that it was tempting to link up again with a manager who had helped so much with his development.
"At the time, if I am honest about it, I did have thoughts about going to Inter," Lampard said in the Daily Star.
"It was a difficult time for me in my life. Things had happened for me personally and everybody knows how I feel about Jose Mourinho.
"It was never a case of wanting to leave Chelsea to go to a team in England - that would be impossible for me."
Lampard has no regrets about his decision to remain at Stamford Bridge and does not think he will ever leave the club now.
"I'd like to finish my career here now, but then I didn't know what I wanted," he explained:
"I thought maybe it was something I could, but it is the best thing I have done, not going to Inter."
Lampard maintains that the support he has always received from Chelsea fans was a major factor in his decision.
He said: "I'll never forget what my mum and my dad said to me at the time, 'Don't forget when you walk away from the ground everyone is singing your name, don't forget what these people have given to a West Ham boy moving across London'.
"That kind of thing made me think and I am positive that I made the right decision."
