Arsenal midfielder Santi Cazorla has hailed the form of Olivier Giroud.
Giroud struck in victory over Crystal Palace.
"He's very important for us in these games, because we sometimes need to play long balls," Cazorla explained. "He can keep the ball and [draw] fouls, and he's a good header of the ball.
"He's in a good moment and I hope he'll continue to play the same way."
