It takes hard work for Arsenal to do something like that even though this match is actually still quite long, but when looking at h2h they are clearly not benefiting too much.
Now in the remaining matches before facing Manchester City they have to focus on bringing 3 points again and again.
If Manchester City manages to maintain the momentum with a win + positive result against Arsenal at the Etihad stadium, Manchester City has a big chance of taking first place from Arsenal. There is no more time to play around for Arsenal in the remaining 8 matches, they must consider all of these matches as final matches that must be won to win a trophy this season.
You're spot on. The mentality of the players is key in these contests. They've got to grind and give it their best shot to rack up the points. But, truth be told, it's easier said than done. The competition can be cunning, and Arsenal must gear up for the unexpected. Having said that, I think Arsenal's got what it takes to emerge victorious if they stay on point and play by the book.
