So it's not a problem for you that under these managers we can't beat these sides that are mid table sides away from home. When you play at home, you can dictate the tempo of the game more because you have the crowd on your side and the team are playing on familiar territory so it makes a difference for these managers.
Because we have managed to get away with draws on occasion doesn't change that and Koeman has beaten Wenger when playing in home fixtures three times in a row with an aggregate of 8 goals for and 1 against....is that really close?.
