Barcelona enters the last eight as the favorite to win the Champions League, mostly due to Lionel Messi's return to brilliance, but the Catalans also go to Paris with an unhappy Neymar, who angrily reacted to being substituted in last Saturday's 2-2 draw at Sevilla. PSG has its own problems with injuries and the absence of Zlatan Ibrahimovic, who is suspended due to a controversial red card against Chelsea in the round of 16.
