So many times I see blue arrows on defenders!, I think doing that all you are doing is giving your opponent the liscence to attack! I personaly dont think defenders need any arrows and so I have never used then in 9 seasons!, your team looks good and very attacked minded I would put a red arrow on the striker aswell and one on the middles center midfield, you are very narrow playing the diamond and he is set up to hit you on the flanks so you will have to be carefull.
