Gael Clichy says Arsenal have their 'spirit and desire' back and feels the club can have a successful season.
Saturday's 1-0 win at West Ham United ensured The Gunners maintained a two-point lead at the top of the Premier League table, and also continued the unbeaten start to the season.
Clichy understands why Arsenal were written off as title contenders in the summer, following the sale of Thierry Henry, but the French full-back is now relishing the rest of the season.
"If we carry on like this it gives us hope that anything is possible for the club," said Clichy.
"I don't know if we're going to be unbeatable, but I'm sure we're going to be up there at the end of the season.
"Nobody gave us a chance at the start of the season and that was fair enough because the last couple of years have been difficult for Arsenal and we didn't win anything.
"But now we have what was missing in the last two years. The spirit and desire to fight for each other is back."
Up for it
The defender also believes that the hard-fought success at Upton Park is a positive indicator for Arsenal's title chances.
He added: "We were really looking forward to this game because every year we struggle here and this time we wanted to come here and do something positive.
"This is definitely the type of result we didn't get last season. Last season we lost only once at home, but were let down by our away form. This time we are showing everyone Arsenal are up for it.
"If we can keep getting away results like this we can do something special because we will always be solid at home."
