Olivier Giroud insists it is too early to tell whether Arsenal can mount a serious challenge for the Premier League title – but says the Gunners are a far stronger team this season.
Arsenal beat Everton 2-1 at the Emirates Stadium on Saturday night to claim their fourth successive victory and briefly go top of the Premier League.
However, Manchester City's goalless draw with Manchester United at Old Trafford on Sunday saw Manuel Pellegrini's side reclaim top spot on goal difference.
Giroud started and scored in the win over Everton and seems to have rediscovered his goalscoring touch following an inconsistent start to the new season.
The France international has bagged six goals in his last seven matches for club and country.
"I don't want to look too far forward because we need to keep it up and carry on this momentum. It's only the 10th game in the league so we've got 28 to go, so it's a bit early," Giroud told the club's official website.
The 29-year-old also said Arsenal's fighting mentality will be crucial if they are to secure their first league title since 2004.
"I think we are stronger mentally this year," he added.
"We are all fighting for each other. We have a great togetherness and we want to achieve big things altogether. We are showing a lot of leadership."
"We are all looking in the same direction and we know we need to be 100 per cent in every game. If someone is a bit tired then someone else will battle and fight for each other. That's the mentality we need to show through the season."
Injured midfielder Jack Wilshere also feels Arsenal do not need to sign any players in the January transfer window as the squad is strong enough to compete for top honours.
When asked if the club needed to strengthen in the New Year, he said: "I don't think so.
"Defensively we look good. We've got Gabriel who has really grown up. Last season, he was settling in. He is really suited to the Premier League.
"We've also got myself and Danny Welbeck who should be back round January and make the team stronger."
