Volz in line for Arsenal start
Volz, 19, has previously started just one first-team game. That was against Ipswich Town in the Worthington Cup two year's ago.
However, injuries to Oleg Luzhny, Lauren and Ray Parlour as well as a suspension to Kolo Toure mean that the German was an emergency call-up to the squad for tomorrow's tie at Roma at the start of the second group stage.
