Zinedine Zidane backs Paris Saint-Germain for Barcelona upset

Real Madrid legend Zinedine Zidane believes that Paris Saint-Germain can beat Barcelona in the second leg of their Champions League quarter-final on Tuesday evening.

Barcelona are the overwhelming favourites to reach the semi-finals after claiming a 3-1 victory in the first leg, but Zidane feels that PSG have enough quality to cause a shock at Camp Nou.

"It will be very difficult for the PSG to score three goals in Camp Nou," Goal.com quotes Zidane as saying.

"They must do it but this PSG team is able to. They have quality players in their team, they are effective and everything is possible in a game.

"It will be the most difficult challenge but hopefully they can do it."

No team in Champions League history has been able to overturn a two-goal deficit after losing their first leg at home.
