Liverpool take on Red Star Belgrade on Tuesday looking to consolidate their position at the top of Champions League Group C.
The Reds returned to the summit of the pool with a resounding 4-0 win over Red Star at Anfield a fortnight ago.
The Serbian outfit have picked up just one point from their three Group C matches so far, but have won two and drawn three of their five European games at home this season, conceding just once. Their opening pool game versus Napoli at the Rajko Mitic Stadium finished goalless.
So where could the game be won and lost in Belgrade?
