The first leg featured four goals, two comebacks, a 37-year-old Englishman and one extraordinarily high-profile hamstring injury. Imagine what the second leg might bring.
Barcelona and Paris Saint-Germain are set to play what promises to be a thrilling UEFA Champions League quarterfinal second leg on Wednesday at Barca's Camp Nou. Last week, an exciting first leg ended 2-2 in Paris, giving Barcelona a slight edge with two away goals and leaving PSG hope of pulling off the upset.
The Parisiens will also take hope from the uncertainty over Lionel Messi and his hamstring. The prolific Argentine forward left last week's match early and is a doubt for Wednesday's second leg.
But that's just one of the storylines that we're looking forward to watching on Wednesday.
