Per Football Italia, he won the award―calculated via statistics―thanks to his 22 goals and 11 assists in 33 matches across all domestic competitions. The award is an official distinction from the league, with Ernst & Young putting the list together using data from Opta Sports and Netco Sports.
Napoli's Kalidou Koulibaly, Lazio's Sergej Milinkovic-Savic, Inter Milan's Samir Handanovic, Sampdoria's Fabio Quagliarella and AS Roma's Nicolo Zaniolo were the other winners, the latter being voted Best Young Player and the others picking up the positional awards.
ESPN FC's James Horncastle was not impressed with some of the picks:
James Horncastle @JamesHorncastle
Ronaldo to be given the new Serie A MVP award before Juventus’ game against Atalanta. Handanovic best GK, Koulibaly best defender, Milinkovic Savic best midfielder, Quagliarella best attacker, Zaniolo best young player. I have an issue with more than one of those awardees
Neither was Serie A writer Adam Digby, who thought the decision to use statistics resulted in some odd choices:
Ronaldo lost out on the award for best forward to Quagliarella, who has scored 26 goals and is likely to finish as this year's top scorer.
Handanovic has been a key man for Inter, playing a vital role in the team's push for a UEFA Champions League ticket. With two matches left to play, the Nerazzurri are in third place in the standings, four points ahead of AC Milan and AS Roma and one ahead of Atalanta.
Koulibaly has been among Serie A's best defenders for years, but Napoli only have the third-best defence in the league this season, behind Juventus and Inter. Zaniolo's award for the Best Young Player also wasn't a surprise after the breakout season he has had.
The oddest pick was undoubtedly Milinkovic-Savic, who regressed tremendously compared to last season. The Serbian has so far scored four goals and added three assists in the 2018-19 Serie A campaign after bagging 12 goals last season.
Serie A writer David Amoyal couldn't believe he got the nod and also thought Salvatore Sirigu or Alessio Cragno of Torino and Cagliari, respectively, should have beaten Handanovic to the goalkeeper award:
Ronaldo's MVP award will also raise a few eyebrows, but not because he's undeserving. Lega Serie A decided to include stats from the Coppa Italia and Italian Super Cup, even though only two teams―Juventus and AC Milan―played in the latter.
If only Serie A stats had counted, the Portugal international would have finished behind Quagliarella, who recorded the same amount of assists―eight―and five more goals.
Juventus will play two more matches this season, against Atalanta on Sunday and Sampdoria on the final matchday.
