The 33-year-old striker scored in both of France's matches against Iceland and Turkey.
With a fight on his hands for playing time at Stamford Bridge, Giroud is determined to continue his stellar international form.
He said: "[Lampard] will almost certainly watch the matches. In any case, I am going back to Chelsea pumped up.
"For different reasons, I have played little since the last national team break. Of course it feels good to make the difference."
