There is nothing to doubt about Arsenal today, a win is the most logical thing to consider. Arteta has emphasized that the team must not lose anything in every match regardless of who they play against, meaning that Arsenal will require themselves to continue to maintain their best performance and get maximum points in every match.
This season, Arsenal still has a chance to win the title, especially because the points gap between the teams is very low. Arsenal just need to think about their performance instead of thinking about other teams, that's what can help them lead the standings if Manchester City and Liverpool slip up.
