Arsenal maybe lacking here in the game against Aston Villa not because they cannot win the game even after such an opponent,they surely can but because they need to save power for the upcoming 2nd leg of the Champions League which they will play in Munich and will have a hard time if they spend to much energy during the game of Aston Villa.It is in Arsenal choice what would they value more,the continuing of a superb form in the Premier League fighting hard for a title that they are a couple of years near missing it or shift focus during this week for the Champions game risking big for their overall fight for the title in the Premier League.
A good team doesn't give excuses, playing hot games is basically what football players are paid to do isn't. I'm positive that Arsenal will play professionally irrespective of the features they have, they will do well in all their next game because not only Arsenal will be playing in their domestic league, every other teams are going to play in their respective leagues and then meet in their second leg of the Champions League. The only thing I don't want to see is injuries from Saka, Rice, Martinelli, Nketkiah, Havertz and Gabriel.
The last time Arsenal met with Aston Villa was in Villa park and I guess Arsenal didn't expect that goal, they were lose on defensive positions but patch that up immediately, but this time they are meeting in Emirate and Arsenal treat them like they are meeting in the final round because Arsenal need all the point they can gather to stay ahead of other teams in the table.
