James Rodriguez scored the late goal that secured victory for the hosts, 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.

"We are disappointed, however, because we wanted to produce a better game here. But that wasn't possible and we must accept it.

"Don't forget we're quite a new team. We need time. On top of that, Porto produced a good performance. To come here and struggle is not surprising. As I said, they are a team with a wealth of experience. Now let's prepare for Marseille [on Sunday]."

Ibrahimovic echoed his coach's thoughts, saying PSG had failed to hit the heights reached during a previous run of five wins in a row.

"Porto are the favourites to win [the group] because they have more experience than us, but we were able to trouble them", he said.

"I think we're learning every game. It's our first time in the Champions League for a long time, and it's different. But we made more technical mistakes than we normally do, and then in the last ten minutes they scored, so we dropped three points."
