Arsenal manager Arsene Wenger believes that his side's home form will be crucial if they are to win the Premier League title.
The Gunners returned to the top of the table after Alex Oxlade-Chamberlain scored twice at the Emirates Stadium to help them beat Crystal Palace 2-0.
Wenger told the club's official website: "We are today where we are, and that cannot be a coincidence. You cannot be lucky over 24 games, that is for sure.
"I think we know that our results at the Emirates will be massively important until the end."
Arsenal travel to Liverpool for their next league game on Saturday.
