The Champions League quarterfinals get under way Tuesday with Barcelona visiting Paris Saint-Germain in a meeting between Europe's most dominant team of recent years and its latest challenger.
After signing star players like Zlatan Ibrahimovic and David Beckham, PSG is anxious for a major victory that would justify its engorged payroll and catapult the French team into the upper echelon of the continent's elite.
Standing in its way is Lionel Messi and Barcelona, which is seeking to add to its three Champions League titles in the past seven years.
Also in the last eight on Tuesday, Bayern Munich hosts Juventus in a clash of former champions. On Wednesday, nine-time winner Real Madrid hosts Galatasaray while Borussia Dortmund visits newcomer Malaga.
