Can Arsenal kill two bird's with a stone
Maybe they can but not with the premier league and Europa league
They need to put in more work so they can at least win the league
Manchester City is Arsenal's main enemy in the Premier League
Meanwhile in the Europa League, several teams such as Real Sociedad, Freiburg, Betis will be at the forefront of prevent Arsenal from winning the Europa League title this season. So far I'm still pretty sure Arsenal are the strongest candidate in the Europa League
There is no doubt in this season Arsenal is strong contender for the two top titles first Premier League where they are right now having five points lead from second spotted Manchester City and in UEFA Europa Cup they have done good job which is clearly indicating they can do good at the end of this season specially their defence and attack both are at the same level and supporting each other very strongly.
Now after break we are going to have tough challenges waiting for them because most chances few clubs are going to increase their firepower which is going to have good change in Premier League, so Arsenal are also having few inquiries if they are able to have positive development then surely we can expect good end of this season from them for their fans.
