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.

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."
