Aubameyang featured for Borussia Dortmund in the Champions League during the first-half of the season, which means that he is not able to play for Arsenal in European competitions until next season.
Aubameyang has three goals in five Premier League games so far - including two in his last two.
'I am really frustrated because the rules are a bit...
This has restricted Aubameyang's chances of settling in north London, and he has voiced his frustrations with UEFA. "I don't know how to say in English, but I am disappointed because I can't help my team", Aubameyang told reporters.
'That's life. I have to deal with it'.
The 27-year-old said: "It's competition and I embrace it".
"When I was in Dortmund, I was playing every three days but now I play once a week or have a long time between games". 'He had the interest in me so I am happy to play for him'.
"My mindset's just focused on looking forward, bettering myself, getting on the pitch, on the training pitch, doing what I can do to improve myself".
"Of course I am really happy because I am here because of him", Aubameyang said.
He is determined to play his part over the final few weeks of the season, with Arsenal still chasing a top-four finish and Europa League glory, while England manager Gareth Southgate is piecing together his plans for the 2018 World Cup.
