The England international says the Gunners are focused on bringing league glory to the Emirates in 2015-16.
The 24-year-old said that Arsene Wenger and his squad know that, with the ability at the club, and having proved how well they can play for most of the year, bringing the title back to the Emirates is the target.
"The way we finished off the season, we want to step up to the next level and go that bit further," the England international told Arsenal Fan TV.
"We want to bring the Premier League back to Arsenal and that's certainly the ambition of the players. We've got a talented squad and everyone's fully focused on going into every single game and then going on to the next game and racking up the points."
Arsenal recovered from a temperamental opening half of the season to blitz the league after New Year's Day.
The Gunners only lost two games after January 1, an away loss to rivals Spurs and a freak home defeat to Swansea after a once in a lifetime performance from ex Arsenal goalkeeper Lukas Fabianski.
In fact, of Arsenal's 18 games that came after the defeat to Southampton on the opening day of the year, Arsenal won 13 of them, meaning they won 42 out of 54 points, or 78% of the points on offer
If Arsenal would have accumulated points at that percentage across the season they would have ended up with 89 points, enough to have beaten Chelsea, and that is the fact Welbeck and his fellow Arsenal players must remember when the new season begins.
Play like they did for the vast majority of 2015, and they will almost certainly win the league.
