PSG ace Neymar felt Real Madrid's experience counted on Wednesday night in their Champions League defeat.
Neymar believes that PSG were made to pay for also being over-confident.
He said, "I think we took a step backwards at various moments.
"We should have been more calm enough and we didn't have the maturity we needed in the later stages of the second half. The team needs that little bit extra and we have to accept that. We didn't put in a bad game but we need to improve if we are to have a chance of turning this around. It's going to be difficult but not impossible. Last season we were in a far more difficult situation to make it to the next round."
