The Frenchman scored twice in six minutes before half time to show double his tally for the season and repay his manager's faith in him.
The first was a cool finish after a fine ball from deep from Toni Kroos and the second a tap-in after unselfish play from Cristiano Ronaldo.
Could this be the springboard the France international needs to finally get his season up and runnning?
