Javier Pastore accused Paris Saint-Germain of lacking focus as they suffered a shock 2-1 defeat to Strasbourg on Saturday.
The Ligue 1 leaders were beaten for the first time this season in all competitions thanks to goals from Nuno da Costa and Stephane Bahoken, either side of a Kylian Mbappe strike.
PSG had 73 per cent of the possession and 29 attempts but rarely looked like denying Strasbourg a famous win after going 2-1 down in the 65th minute, when Bahoken raced through to score after a goal kick was flicked on by Nuno.
Pastore was frustrated to lose in such a manner but hopes the result serves as a wake-up call for the rest of the season.
