Arjen Robben admits Bayern Munich is nervous as it heads to the war-torn Ukraine for Tuesday's Champions League last 16, first-leg, clash against Shakhtar Donetsk.

Due to fighting in east Ukraine between government forces and pro-Russian rebels, Shakhtar hosts its home league games in Kiev but has opted to play its Champions League matches in Lviv, near the Poland border.

It will host Bayern at Arena Lviv, about 1,000 kilometers from its own Donbass Stadium in Donetsk, which is being used to distribute humanitarian aid and whose facade has been damaged by shelling.
