Podolski is mainly a striker and should be used as such . He can operate at the left wing and be efficient if he is supported by a good left back . But in our point of view where a left back is always a calamity it means Lukas should be converted as a left back no 2 to limit the damage and hence limit his attacking threat . He is being made to work harder than he should and condemning Arsenal not to fully benefit his ability . Should we sign Messi next time and make him a central defender ?
