With Chelsea making up ground by winning 3-0 at Southampton, the league's three unbeaten teams go into the global break locked together on 20 points.
Lacazette, however, wants to silence any chat of such an achievement and focus on doing the things which have enabled Emery to oversee such a streak.
"We have to keep quiet and work like we did before and the season is going well".
The Welshman will be free to hold talks with clubs outside England in January and sign a pre-contract with a view to leaving Arsenal at the end of the season.
The win was Arsenal's ninth in succession in all competitions - their best run since stringing together eight successive wins from March to April 2015 - and put them into the top four. "It is very hard but we must prepare, continue improving and show big commitment", said Emery.
No first team player has crossed the divide since Sol Campbell in 2001 and he has been a hate figure ever since for Spurs fans. "The best performer for us is every player".
Aubameyang had joined Arsenal in January, scoring 10 goals in 15 games for the North London side.
"It is good", Lacazette said of his relationship with Gabon global Aubameyang.
Describing Aubameyang as his brother, Lacazette says he is positive his brother will score as many goals as possible at the Emirates Stadium.
"Riyad feels deflated, he feels he has let us down", he said.
"But I hope Auba scores as many goals to help us win something". If you believe the solution is sit in the box and try find the solution in this way, I don't believe in this way.
