Ronaldo scored two goals as Real Madrid eased to a 3-0 win over Juventus in the first leg of their UEFA Champions League quarter-final clash on Wednesday (AEST).
And while his first goal was predatory, his second was pure magic or - in the words of James - just plain "nasty".
"Are you not entertained!?!?!," James said via his Instagram.
"@Cristiano that's just not even fair. Nasty!!"
Manchester United's Marcus Rashford echoed James' sentiments on social media, tweeting: "Cristiano Ronaldo is a joke. What a player!".
As did AC Milan legends Ruud Gullit and Franco Baresi.
Ronaldo has now scored in a record 10 consecutive UEFA Champions League matches and took his overall goal tally to 39 across all competitions this season.
