Arsene Wenger has insisted the race for the Premier League title is far from over, despite Arsenal already trailing Manchester United by 11 points.
The Gunners have endured their worst start to a campaign under the Frenchman, having lost three of their five league games, including an 8-2 mauling by United at Old Trafford.
In contrast, the defending champions have chalked up maximum points.
"If the team gets momentum, we can be very strong," said Wenger.
"Of course I am worried. It is absolutely not realistic not to be worried when you have a team like Manchester United in front of you."
Wenger, though, maintains it is far too early to be writing anyone off.
"The only thing we can do is focus on our performances, win our games and hope they will drop some points at some stage," the Frenchman added.
"However, at the moment I am more concerned by us than them. If they do a perfect season, they do a perfect season. Until now, only one team did that - Arsenal."
Wenger was referring to Arsenal's unbeaten 2003-04 league campaign, and accepts at the moment that just rediscovering the winning feeling is the priority for his side.
"What is important for us is to give absolutely everything to do it [win the title], but at the moment it is too early to speak about that," he said.
"Let's come back to a better distance with the top teams before we speak about that.
Wenger lambasted his squad for the way they self-destructed in their 4-3 defeat at Blackburn last weekend, scoring two own goals in the second half after they had led 2-1.
The Frenchman will expect a response from the rest of the squad on Saturday against a Bolton side who have lost four league games on the spin.
