For Manchester City, Arsenal draw gives them the opportunity to reduce the lag in the upcoming match.
there is a gap of 6 points now so it will be easier and closer, there are several games left in the season and if Arsenal lose or draw of course manchester city will benefit because manchester city are starting to be consistent in their winning ways to overtake Arsenal at the top of the table and take it, currently manchester city is preparing for the UCL match against Bayern, of course they have a lot to prepare.
Arsenal team is in great form in the English Premier League. The team is able to perform quite well in the rest of the leagues as well. However, some matches Arsenal have disappointed the fans. But I am sure Arsenal team will do great things this season.
