Barcelona - Paris St Germain coach Laurent Blanc accepts his side face an almost impossible mission trying to turn around their Champions League quarter-final against Barcelona at the Camp Nou on Tuesday.
The Ligue 1 champions were swept aside in their own stadium last week by a dominant Barca led by a lethal Luis Suarez who grabbed a brace in the 3-1 defeat.
They have Zlatan Ibrahimovic and Marco Verratti back from suspension for the second leg but Thiago Silva joins Thiago Motta among the injured and David Luiz is also a fitness doubt.
