Santi Cazorla says Arsenal have what it takes to become champions, but they must keep hold of Hector Bellerin if they are to win the Premier League.
"We have started the season in a good way," Cazorla told IBTimes. "We are having a good run but it is a very long season. We have to go step by step. It is clear that we want to fight [for the title].
"We have always said we needed to give a step forward. We have started well and we are being more consistent. That's what we lacked in previous seasons."
Cazorla also reckons keeping hold of Bellerin - who joined Arsenal from Barcelona as a 16-year-old in 2011 - will be key for the Gunners as they cannot afford to lose the full-back like they lost Thierry Henry, Cesc Fabregas and Robin van Persie.
"It is clear that Hector is the right-back of the future," Cazorla added. "You could see in the victory over Swansea how good he is. He was all over the place and never stopped running.
"For Arsenal it would be a mistake to let him go.
"It is obvious that many teams want him. There has been talk about Manchester City and Barcelona.
"He is a player with great potential and I am sure he will also be a key part of the future of the Spanish national team."
