The hosts reduced the deficit in the 82nd minute when Jeremy Mathieu deflected Gregory van der Wiel's shot into his own goal as PSG suffered their first loss at home in Europe since 2006 ahead of the return leg at the Nou Camp next Tuesday.

In the absence of the injured Thiago Motta and the suspended Marco Verratti, Yohan Cabaye and Adrien Rabiot were fielded alongside Blaise Matuidi in the PSG midfield and the trio's collective lack of Champions League experience showed.

PSG started confidently with the classy Javier Pastore delighting the crowd with delicate twists and turns, but after 18 minutes, the home side were 1-0 down and they had lost centre back Silva.

Lionel Messi almost opened the scoring in the 13th minute when his beautifully curled shot from just outside the area smashed Salvatore Sirigu's right post, but he was more accurate seven minutes later when he set up Neymar for the opener.

Rabiot lost the ball near the touchline to Sergio Busquets, who found Messi in midfield. The Argentine played Neymar through and the Brazil striker coolly finished from close range.
