Arsenal boss Mikel Arteta says his squad is very compared to the last time they visited West Ham.

Speaking to the media before Sunday's game, Arteta said he hoped the side had 'improved a lot' since that dramatic 3-3 draw last season.

"Especially what we did in the first 20 or 30 minutes," he said. "We put ourselves in a really difficult position. It's true that we reacted phenomenally well, but we want to start the game in a different way."

Arteta went on to outline how the team, and the club in general has changed over the past 12 months.

"We have very different players in the squad and we have a very different environment," he said, without naming the likes of Pierre-Emerick Aubameyang and Mesut Ozil. "I think the unity that exists right now between the team, the staff, our supporters and externally is completely different and is very, very beneficial for the team.

"Obviously, how the team has evolved in its understanding of what we want to do is much better.

"The execution of it is much better, the consistency of results is better and what we're trying to do is seek for improvement every single day and probably what we did a year ago is what you see now."
