Giroud was given his international debut by Blanc in 2011 but, while suggesting that he would not be averse to the appointment of the ex-Paris Saint-Germain manager, he is unsure about the truth of the rumours.
"I do not know at all," he told reporters when asked to comment on the recent press reports. "I hear things being said, but as long as it's speculation, we do not know, we'll see.
"Blanc knows me, he trained me, but it is Antonio Conte who made me come to Chelsea. Antonio Conte is under contract, I do not and will not talk about a new coach."
