for me what is badly lacking for us at the moment is pace, i think Giroud is spent and he should not be starting again for us this season.

If it was me i'd play Podolski up front with Sanogo and Gnabry on the wings, Sanogo can't play up front on his own his first touch is shocking but i reckon he could run in behind some of the sides we have left this season and lay a few on for Podolski to finish.
In midfield for Tuesday at least play Ox, Cazorla and Rosicky...Arteta cannot be allowed to play for us ever again.
Giroud is the kind of player who can still have a role to play if we are leading a game, his best goal scoring contributions in the last few years have been when he has been brought on from the bench when we are leading.
