"I'm the best player in history - in the good and the bad moments".
Nearly a goal made in Los Merengues' youth academy saw Marcos Llorente volley Achraf's chipped cross just wide, before Rico managed to smother the right-back's one-on-one in the nick of time. A defensive mix-up between Simon Kjaer and Luis Muriel at a subsequent corner allowed Nacho to tuck in from close range.
Sevilla didn't play badly, but Ever Banega was on a tight leash.
Overall, Ronaldo scored 42 goals and assisted another 12 strikes in all competitions for Zinedine Zidane's side and was particularly influential in the latter stages of the campaign, netting 10 goals in the Champions League knockout stages to help Real become the first side to defend the title.
Lionel Carole's deflected effort flew wide of the mark for Sevilla in the 15th minute, and Banega's free-kick almost found a target.
Unsurprisingly, the newspapers in his favoured regions lead on a picture of Ronaldo with Marca's accompanying headline translating to "I want seven" after he declared his intention to win two more before retiring.
The former Real playmaker added: "He'll always be up here for me".
The Portuguese quickly grabbed his second goal after Marcelo's hooked ball in the box was clearly blocked by Jesus Navas' outstretched arm, the No 7 sneaking the penalty just under Rico to the right.
And the onslaught continued. The Bernabeu didn't mind, cheering every pass as the visitors chased the ball.
With time ticking away, Rico made a fine diving stop to keep out Hakimi, and that was the final chance of an entertaining contest.
Madrid were ahead inside three minutes through centre-back Nacho Fernandez's neat turn and shot, with Ronaldo making it 2-0 midway through the first half with an expert finish from a sublime Marco Asensio assist, and the five-time career Ballon d'Or victor soon getting his second from the penalty spot after a Jesus Navas handball. Los Blancos are sitting third with 31 points, three points behind Valencia, and will visit Leganes in their next outing.
