Paris Saint-Germain boss, Laurent Blanc, believes there was little between Chelsea and his side, but ultimately the Blues' experience was the key for their progression.
PSG carried a 3-1 advantage from the first leg to Stamford Bridge, but were for the second consecutive year eliminated on away goals after Andre Schurrle and Demba Ba scored for the hosts.
Blanc, who had announced his side will win the Champions League ‘very quickly’, rued the missed chances and the late punch by Chelsea.
"Overall, in my opinion, the difference was not huge," Blanc told UEFA's official website.
"We could have gone through but, unfortunately for us, it's Chelsea who do. But the level of both teams, in my opinion, was very close.
"Over the two matches there was very little between the two sides - ultimately, though, I think Chelsea's experience of playing at this level of the competition made the very small difference."
While Chelsea gained confidence, PSG had their chances through Edinson Cavani, who missed two great opportunities when the tie was still 1-0, and Peter Cech saved another one by Marquinhos late in stoppage time.
"Ironically, we started better in the second leg than the first. In the first 25 minutes we were fine.
"We conceded a key goal from a throw-in and that put us in big trouble, giving confidence to Chelsea.
"Then, in the second period, they tried to pile pressure on to make us suffer. Unfortunately we did not take our chances."
