Protecting three-goal leads, Champions League heavyweights Real Madrid and Paris Saint-Germain will look to clinch their places in the quarterfinals on Tuesday. There's a one-sided look to the first batch of second-leg matches to be completed in the round of 16, as Madrid and PSG arrive in England with a 3-0 lead over Manchester City and a 5-2 lead over Chelsea, respectively. This could be a tough week for the much-hyped Premier League, as all six of its round-of-16 representatives failed to win across the first legs.
