Manager Mikel Arteta challenged his Arsenal players to maintain their mindset following the international break after they beat Crystal Palace to go eight points clear at the top of the Premier League.
The Gunners have won six consecutive league games as they aim to become champions for the first time since 2003-04.
They have 10 matches left, including clashes with Liverpool, second-placed Manchester City, Chelsea and Newcastle. Their next game is against Leeds at home on 1 April.
“We can control our games. We have won six games in a row in the league, which is great,” said Arteta.
“It feels very good, especially with the way we have played and the results we have picked up.
“Now we must stop and make sure everyone comes back from the internationals with the same mindset. We have Leeds next and we put the focus there.”
