The 26-year-old missed three months of the season due to a knee injury he sustained during a 2-0 defeat to Chelsea back in October.
Özil was coming off the back of a busy summer where he stared in Germany’s World Cup win in Brazil.
“It was a very long season. I guess it was the hardest in my career,” Özil told Kicker.
“The first time in my life I had to deal with a serious injury. It feel it was a consequence of playing a lot games without a break over years.
“I was happy with the second half of the season. I wanted to show everybody that I’m back. Winning the FA Cup means it was a successful year. I’m proud of that win.”
Özil did however return from his injury stronger than ever. The World Cup winner has won two Vitality Arsenal Player of the Month and a PFA Fans Player of the Month award since the turn of the year.
The 26-year-old also lead his side to FA Cup success for the second time in two years.
Özil provided nine assists and five goals in 32 appearances for Arsenal in all competitions this season.
