Manchester City defender Kolo Toure insists it is too early to compare Roberto Mancini's team with Arsenal's historic Invincibles side.
City are five points clear at the top of the Premier League and undefeated after 13 games this season.
But Toure, who was a member of the famous Gunners side that went unbeaten throughout the 2003-04 campaign, has warned his team-mates not to get carried away by the record.
He said: "We started very well but now we just need to forget about it. Just try to win game by game, and as long as you play game by game, it's fantastic.
"We don't think about this record. We just want to play as well as we can every single game.
"When you start thinking about it, you play without control. For me, we just need to relax, go out, do our best and win the game.
"At Arsenal, we never thought about it, it never came into my mind. It was taking it game by game and trying to win."
Toure faced his former club on Tuesday night when Sergio Aguero's winner knocked the Gunners out of the Carling Cup to see City progress to the semi-finals.
Arsenal have gone six years without a trophy but the Ivorian believes Arsene Wenger's men can still secure silverware this season.
He said: "Definitely [they can win something]. They have young players working really hard, they played very well.
"It's magic: Mr Wenger brings in any player and makes them better. Credit to him because he's a fantastic manager.
"It's different. He knows how to see young promising players and that's a great quality for him.
"Emmanuel Frimpong was fantastic, Alex Oxlade-Chamberlain was good as well. All of them were fantastic - they made us work really hard but at the end we had the killer goal."
