Former Arsenal midfielder Ray Parlour believes Alexis Sanchez would be the only player who could have made it into the famous Invincibles side in the 2003-04 season.
However, he insists they do not need someone like Thierry Henry up top to win the title but another Tony Adams, who can act as a leader on the pitch.
The Gunners are on a 10-match unbeaten run in the league, winning nine games and drawing one against Chelsea and are on the verge of claiming second place, their highest league position in almost a decade. Sanchez has scored 24 goals this season, a a brilliant return for a player in his first year in the Premier League.
The Invincibles went on a 49-game unbeaten run, while winning the league, the last time under manager Arsene Wenger. The Gunners are looking to forge a similar team in the coming transfer window to end their title drought, which has extended to 11 years.
However, Parlour believes they are still some way off the top and need more players similar to the likes of Patrick Vieira and Ashley Cole to take on Premier League winners Chelsea.
"I don't think the full-backs would be good enough. Lauren was a great underrated player, and Ashley Cole was fantastic," said Parlour. "I really like Laurent Koscielny; he's improved so much. I could maybe see him getting a game instead of Kolo Toure, alongside Sol Campbell. You could make an argument for that, anyway.
"As for up front, none of them would have any chance of replacing Bergkamp or Henry. Not a chance. In midfield, Vieira and Gilberto did a great job and Pires was a very good player. The only one I could really see getting in would be Sanchez, on the right side of midfield."
On their summer transfer plans, Parlour added: "If I could pick one Arsenal player I played with to put back into the side now, who would make the biggest difference to the current team, it wouldn't be Henry, Bergkamp, Vieira or Pires. It would be Tony Adams. It's not just that he was a great defender, he was a real leader too. Sometimes you need that on the pitch.
