Liverpool's UEFA Europa League campaign resumes on Thursday as they make the long and arduous trip to East to Russia, for their Round of 32 first-leg fixture against Zenit St. Petersburg.
The Reds might have been hoping for a rather more favourable route through the next two rounds after coming out on top of the group stage, but it looks like they will have to do things the hard way after being drawn against Zenit first of all, with the winners likely to have to play Dnipro Dnipropetrovsk in the next round.
Forgetting a possible tie with the Ukrainian side, Zenit will provide stern opposition for the Reds to find safe passage from this stage of the tournament.
With the game coming just three days after the West Brom league game, and only another three days before Liverpool play Swansea at home, it is unlikely that too many senior first-choice players will be asked to make the long journey for the Europa League match.
It could therefore be a case of the senior fringe players and a number of youngsters being asked to repel a strong Zenit side with a number of key players.
Here are five of the most important players that Liverpool will have to watch out for.
