The forward does not think that his side should have even had to face Barca in the final...
His comments come in the wake of Manchester United's 2-0 final defeat to the Spanish side in Rome.
Ronaldo told Portuguese television channel RTP that he does not think his team should have had Barcelona to contend with in the first place.
"I have the experience already to endure all the pressure. It is always bad to lose, whether against Chelsea or Barcelona, who had some luck, as they did not deserve to win the semi-final against Chelsea."
The Portuguese star did go on to say, however, that "it is important to give credit to Barcelona" and admitted that "everything was bad" from United's point of view.
With regards to his battle with Lionel Messi, which was built up by the media beforehand, he said that he was neither "pressured [nor] disturbed".
Nevertheless, the Argentine came off the better of the two players, as he scored the second goal in the match to give his side a crucial buffer.
It is the first time that a Spanish side has won the treble, and the third time that Barca have lifted the European Cup.
