Lampard has spoken of his anguish at missing England's Euro 2012 campaign through injury. The midfielder was forced to miss the tournament after pulling a thigh in the build up.
"It was a huge disappointment at the time. I was devastated, having come off the back of our huge Champions League win," said the veteran.
"I was bouncing when I joined up with the squad and really looking forward to the Euros and playing a part, whatever that was going to be.
"I got injured on the second day but looking back now it means I've had a good old rest which is something I don't normally get. But personally it was frustrating watching the tournament and frustrating seeing us get knocked out.
"But maybe it was something in the bank for me in terms of resting my legs through the summer. I'm very keen to continue playing for England. I'm just not a person who wants to retire at an early age.
"If I don't play for England any more it's either because they don't want me and they don't pick me or the fact that I can't give what I want to give in an England shirt.
"And I don't feel that yet. The minute I do then I'll go. There's no ego of trying to hang around for caps. I've got 90 so 100 is there.
"But I wouldn't want to be there as a charity case and they're rolling me out just to get to a hundred. There's a great group of players who have won 100 caps and of course that's something you strive for when you get towards that figure.
"But I'm very proud of what I've done with England. I've played 90 games and if I didn't play another one I'd still be very proud."
