Arsenal boss Mikel Arteta admits he's never experienced a group of players as he has with his squad this season.
The Gunners go to Tottenham today as Premier League leaders.
Arteta said: “It's an incredible dressing room that is just a joy to work with every single day.
“Some of the things we've done together, probably I'm never going to be able to do them with any other team and any other group. Especially on matchdays. There are things we do together that will be resting in my brain for the rest of my life and probably it's the same for them as well.
“At the end, the job is about the people around you. There is some suffering, there are some beautiful moments, but there is a lot of learning as well. I feel so grateful and very lucky to be in the position I am. There are tough moments and you have to take the bullets, and you have to know they come with your job."
Asked what the biggest single change has been in the last year, he added: “We win more games, which is the most important thing.
“That is the thing that changes everything and we play better. We deserve to win the games we've won and, probably, that's the most relevant thing.
“The players are certainly more mature and the demands have changed as well. My role and the things they need from me are different now. That's why we always have to be evolving and to try to be ahead of what is coming, so we can give to the players and the rest of the staff what is going to make everything click to be more efficient and to win more games."
