“It's a personal thing, I don't want to get involved.”
Blanc on Nasri's goal celebration
who was awarded the man-of-the-match award, was delighted to have beaten his Manchester City team-mate Joe Hart with a 20-yard equaliser six minutes before the break.
"When Franck Ribery gave me the ball, the England defence was sitting back," said Nasri.
"I decided to take a shot but Joe Hart knows me from Manchester City and knows that in that situation, I normally open my foot. This time I closed it a little bit so I am happy with how it worked out."
Nasri celebrated scoring by putting his finger to his lips, with press and Twitter speculating about who the gesture was aimed at.
"It's between him and his critics," said Blanc. "It's a personal thing, I don't want to get involved. He was happy to have scored a goal. You'll have to ask him to whom it was addressed."
