Bernd Leno says he is ready to build on his Arsenal debut and push to become first-choice goalkeeper after a" frustrating" start to life at the club.
The 26-year-old joined the Gunners from Bayer Leverkusen in the summer but had to wait for Thursday's 4-2 Europa League win over Vorskla Poltava to make his debut.
Petr Cech has been Gunners boss Unai Emery's preferred choice in their opening Premier League games, but Leno is looking to secure a regular spot.
Asked if he had been frustrated at being made to wait to make his debut, Leno replied: "Of course, because I came to the club to play every game.
"But I think to move to a bigger club, another country, it needs maybe a little bit of time. It is a little bit frustrating but I keep calm and work very hard to improve.
"I think my performances in training are good. I train very hard and maybe it needs a little bit of time. I keep calm. My chance will come.
"I came for the Premier League. I think it is the best league. The Bundesliga is good but the Premier League is better so I will look forward to playing anytime in the Premier League."
Leno - who has six Germany caps - revealed Emery has not come to a specific arrangement with his goalkeepers over who will play in which matches, and added that he has a good working relationship with Cech.
"The coach always makes the starting XI based on the performance," he said.
"I think it could change, not every week, but he will change a lot. He didn't say the Premier League is Petr's competition and the Europa League is mine. I will work hard every day to play more games.
"We have fun together. We push each other and I think the competition with us is very good. We both can improve and it's still going.
"Of course, [Petr] is a big personality. He had a big career and is still a very good goalkeeper - it is very good to work with him and for my development it is very good to have the competition with him."
