There have been contradictory reports over whether Blues owner Roman Abramovich is prepared to offer Lampard a new contract to extend his 12-year stay beyond the end of the season.
But while that issue rumbles on, the 34-year-old has enjoyed an impressive run in front of goal, including netting in each of his last four games. He struck his 27th goal in 94 England appearances last week with the winner against Brazil and also scored against Wigan on Saturday, taking his Blues tally to 198 and within four of the club's goalscoring record.
The goal against the Latics was his ninth in his last 14 Chelsea appearances as he has found his form after missing the whole of November with a calf problem.
"It's not rocket science: the more you play you get sharper and you get match fit," Lampard told Chelsea TV. "Since I've been able to play regularly I feel like I've got sharpness and the confidence.
"I'm 34, you still need confidence of playing regular games. It certainly helps me, to get flow in your game; you ask any player that, I'm not on my own there.
"When you're playing regularly and you do start playing well, scoring goals, whatever position you're in, it's enjoyable to keep playing and it helps.
"You have to have an eye on the squad - it is a long season - so I'm not expecting, or asking, to play every single game. (But) it seems to me recently I've been able to play every three or four days, I've enjoyed it."
