Granit Xhaka says Arsenal can't afford another poor start to the season.
The Gunners lost their first two matches of Unai Emery's debut season.
With Newcastle and Burnley up first this season, Xhaka wants to see an improvement from his side.
"We now know Unai for one year," said Xhaka. "We know how he wants to play, the philosophy, the ideas.
"It is not easy if you have a new staff and to take the ideas so fast but now it is the second year. We know what we want, he knows us better than last season and what is important is to start very well, to take the three points in the Premier League.
"Last season we lost the first two games, and this season it is important to start well.
"We start the pre-season very well. We work very hard and we do a lot of tactical things, where we were not so good last season. You can see we have a good spirit. The young guys give everything. The players want to give them more experience, to help them. We are more and more together now but in the end we have to be ready for the Newcastle game."
