Arsenal's manager Arsene Wenger has called on his side to maintain their consistency following their 3-1 win over Stoke City on Saturday.
Wenger's side are unbeaten in their last 14 games in the English Premier League and face another big test against Manchester City next Sunday.
"They started well, but we dominated in the second half," Wenger said during his post-match press conference.
"We want to be in the fight. We're on a good run with momentum and we have to do the same in every game in the Premier League."
Three well-taken goals from Theo Walcott, Mesut Ozil and Alex Iwobi cancelled out Charlie Adam's opener and condemned Stoke City to their fifth defeat of the season.
"The key was not to let frustration into the game and keep our nerves and our composure," Wenger added.
"I have top quality on the bench – there is not one player you can question on the bench today."
Arsenal currently lead the log with 34 points from 15 games ahead of Chelsea with a superior goal difference.
Wenger also revealed that Shkodran Mustafi will be out for at least three weeks after sustaining a hamstring injury during the encounter.
"It looks like a good hamstring strain 'good in the bad sense. The minimum is 21 days. That means he will have a nice Christmas."
Mustafi will miss upcoming fixtures at Everton and Manchester City, as well as home matches against West Brom and Crystal Palace.
