His goal now is to turn the club's 16-odd match into a winning.
When Germany was internationally signed in the summer from Bayer Leverkusen for £ 19.3m, it was assumed that Petr Cech's days as the first choice at the Emirates were numbered.
However, boss Unai Emery initially stuck to the 36-year-old, and it was only when Cech was injured in late September that Leno finally made his Premier League arc.
Since then, however, he has not looked back and after keeping Arsenal in play against Wolves yesterday, he feels his continued presence in the Premier League starting line-up is a sure sign that he has stolen pole position in Emery's mind.
"I think I'm playing in the Premier League now, this is the most important contest for the team, for the club and also for me," said Leno.
"Emery has not said anything, but I now know that I will play in the Premier League so I always prepare for these games.
"I'm happy and proud of this and I want to show the boss that this is the right decision."
Certainly it was Sunday, but a hard point in the home is not enough in Leno's eyes if Arsenal intends to be a real title challenger.
"Now we are unbeaten in 16 matches and going to the national team with a losing game would not have been the best feeling," he said.
"But I think in the coming weeks after the international break we have to win games because today we lost two points and we need more to enter the four best at the end of the season, especially at home.
"During the second half we played very well but I think at the end, the result is not the best for us because we wanted to win at home.
"We had a chance to get closer to the four best, and yes we missed it. I think it's a disappointment."
The first half of the Arsenal, however, was characteristicly bad – only Gunners and Cardiff are still available half past time this season.
On Sunday, it was despite a moral-enhancing FaceTime chat with Danny Welbeck before he started kicking when he began his recreation from the surgery on his broken ankle he was undergoing on Friday.
"We talked to him before the match," Leno revealed. "We had a FaceTime session with him.
"It was very good, we wanted to win for him. We are all sorry for him for his injury and hope he will get a good recovery and see him on the plane because he is an important player for the team and also in the locker room.
"He looked very happy and I think he was happy to talk with us because he is still a big part of our team and we will support him to be good when he is injured.
"It's a great quality for the boss because he always wants a team not just a player, and another player and another player.
"This meeting was very motivating for us and for every player to play for Danny because everyone likes him."
