Its funny joke for Arsenal's fans have zero UCL champion league trophy and have been twenty years more without winning yet the domestic league tittle or Premier League. I don't think surprising when Arsenal success defeating PSV at first leg match with bigger score but if qualifying to quarter final round have to face top opponent teams between Madrid or Atletico.
Arsenal have difficult for winning premier league this season after 15 points remaining from Liverpool, however after eliminating at Champion League make The Kop focus for winning premier league and seems small chance for Arsenal removing Liverpool from the top standings.
I don't know how Arsenal are going to do it this season but I will save them the time of trying to win any trophy this season. They are not winning the Premier League because right as it is, Liverpool is out of the Champions League and now they are coming back fully to Premier League where they will want to win the trophy no matter what, Arsenal can't win this against Real Madrid.
If Arsenal really want to win trophies, I geues sits they sit down, analyze and looks for the best players any team could have, that's what Arsenal need and not all this petty petty players they use as midfielders and strikers with wingers, not ell really change.
