I don’t like to hide, and I will keep working hard in order to achieve our goals.”The draw leaves Arsenal seventh in the Premier League table, with eight points from five matches.Next up for Arsenal is a trip to Germany to take on Eintracht Frankfurt in their Europa League group stage opener on Thursday before hosting Aston Villa in the Premier League next Sunday.
