Former Arsenal defender Martin Keown believes the team is being revived under manager Mikel Arteta.
He wrote for BBC Sport: "There have been a few false dawns for Arsenal fans - days where we, wrongly, thought we had got 'our' Arsenal back again.
"Sunday's brilliant win over Tottenham might turn out to be just another one of those days, but maybe there's something different this time that means we can sustain it.
"We certainly got the fans back, for starters. There was an amazing atmosphere at Emirates Stadium, and the Gunners supporters played a big part in what was a complete performance. I would have loved to have been there to sample it for myself.
