Mohamed Elneny kept his place in our midfield for Saturday's 3-0 win at Fulham - and he vindicated Mikel Arteta's decision with another solid display.
Our Egypt midfielder is back in the group after spending last season out on loan, and he has noticed a significant change since he was last a regular.
"We feel like we are more aggressive, like everyone just wants to give 100 per cent," Elneny told Arsenal.com.
"This was what we missed in Arsenal, because at Arsenal we always loved to play football but we didn't care [enough] about giving 100 per cent. But now we can see that everyone does, even the kit man!
"Everyone has to give 100 per cent because this is a great club and everyone has to work really hard to push this club to win the Premier League, to win everything, because we have quality players, we have the facilities, we have the family. Everyone is great in this club."
Elneny has been linked with a move in this transfer window but Arteta has been impressed by the 28-year-old.
"I feel really happy and I have to thank Mikel Arteta for giving me a chance to play," said Elneny.
"I know it's not easy to be on loan and come back to Arsenal and I'm really happy because I made everyone feel like I was not away from the team. This makes me really happy and I have to thank Mikel Arteta because he helped me a lot to feel like this.
"He speaks to me always, saying things like 'we need you on the team' and he is always giving me good feedback and always pushing me to get the best from me. I'm really happy to be here.
"I'll give 100 per cent every day in the training and if they give me a chance to play, I will always give 100 per cent. Because it's the best for me, to play always in regular games and to give 100 per cent to the team, to help the team to win and make sure that we're going to build a team to be strong in the Premier League."
