Mesut Ozil is confident reaching his best this season at Arsenal.
Ozil was criticised by large sections last year after struggling with form and injuries at times.
"I'm very confident because I know the potential I have. We've become more mature and we've learned from our mistakes. If we stay fit and healthy, anything is possible.
"We have big ambitions, you can't be satisfied in finishing second or third or making the round of 16 in the Champions League.
"I missed playing football while on holiday, I'm pleased we are underway, we want to reach our ambitions. We need to be a team, believe. Then we can achieve it."
