Olivier Giroud says he will continue to deliver when called upon by Chelsea manager Frank Lampard.
The Frenchman has hardly played this season due to the performances of Tammy Abraham and Timo Werner.
But the veteran striker came off the bench to score a late winner against Rennes on Tuesday, booking Chelsea's place in the Champions League knockout rounds.
"We must continue this good run, we won tonight, even if it was with difficulty," Giroud told RMC Sport.
"Obviously for an attacker when the coach brings you on you have to bring something, now I am staying concentrated on what I have to do.
"When he calls on me, I do the job, nothing more."
