Olivier Giroud admits he's struggled for self-belief at Arsenal.
The Frenchman hit a brace in their FA Cup win over Middlesbrough on Saturday.
"To improve as a player was my target when I signed for Arsenal, I always wanted to improve myself and give everything for the team, for the fans and the club," he said.
"I try to give my best every game, sometimes it goes easy, sometimes I struggle a bit more, but it is always a determination, I try to keep it high in my head, because it is my worst enemy.
"(I am asking myself) am I ready or am I not? The boss told me that before and sometimes I need to push myself a bit out of my comfort zone."
