Paris St Germain suffered their first defeat of the season as they lost 1-0 away to Porto in the Champions League on Wednesday.
James Rodriguez scored the late goal that secured victory for thehosts, leaving PSG coach Carlo Ancelotti to tell reporters he believed a lack of experience had cost his team.
Although big-spending PSG included Thiago Silva, Gregroy Van Der Wiel and Zlatan Ibrahimovic in their line-up, they failed to make much impact against the two-time European champions.
The defeat leaves PSG on three points - three points behind group leaders Porto - and Ancelotti said: "Yes, it's our first defeat this season. But it's no wonder we lost because we faced a team more experienced than we are.
PSG simply needs time.With the callibre of players they have,they will surely nick something this year
