Midfielder Declan Rice believes that Arsenal need to build a stronger in-game mentality after the north London club dropped points in back-to-back matches.
Arsenal suffered a 2-1 defeat against Fulham on Sunday, damaging their Premier League title chances.
Arsenal didn’t take advantage of an early lead given by Bukayo Saka at Craven Cottage, dropping down to fourth position with 40 points at the halfway stage of the campaign.
The Gunners also lost 2-0 at home against West Ham United on Thursday.
"When you go 1-0 up, you need to take more control and have more self-belief," Rice told Sky Sports.
"You need to have more desire, the mentality needs to be better. We need to demand more for each other.
"In this league, there's no room to mess up. There's so many good teams around you and we want to be pushing up the top end of the table. It's a tough one to take today."
Aston Villa have 42 points, the same as Liverpool, who lead on goal difference and will face Newcastle United later on Monday, while defending champions Manchester City are third with a game in hand.
"There's a lot of media who talk and say 'Arsenal will win the league this year, Arsenal are better this year', and whatnot. But we don't get involved in that, we just try to take every game as we can, one by one," Rice said.
"We've been doing really well. There's been a blip in the road, but there's no room to panic. There's still so many games to go, we need to stay positive. It's not the time to be negative."
