Red card undeserved but part of 'learning curve' for Dowman - Pennant

I can understand Arteta's frustration because he probably the game plan would have said right do not retaliate do not bite do not go down to their level because that's what they're going to do they're going to want any advantage and they're going to wind you up they're going to kick you they're going to be horrible you know just be professional stick to your game we've all been told that before these kind of games but I think Arteta maybe should have looked at the incident in itself and realize it actually wasn't a red card it for me shouldn't have been a red card it didn't really make it wasn't aggressive it wasn't anything malicious it wasn't you know didn't put anyone in danger and the tackle on him was the worst part of all of it um so yeah maybe he should have really looked at that really and um the dismissal was a little bit harsh but again it's going to be a learning curve
