The 36-year-old returned to Old Trafford last month, 12 years after he left the club for Real Madrid. Ronaldo's return was termed as a "homecoming" and he outsold all other Premier League players on shirt sales within 12 hours, but according to research carried out, his move has not been universally popular.
Based on reactions, Ronaldo's return to United was only the 22nd most popular post on social media, despite the attention it garnered. Chelsea's signing of former Fulham goalkeeper Marcus Bettinelli ranked first, with a whopping 99.6 percent positive reactions.
Fiyako Tomori's move from Chelsea to Milan and Albert Lokonga's move from Anderlecht to Arsenal ranked second and third, respectively, while Jack Grealish's £100m move to Manchester City ranks fourth, and Raphael Varane rounds off the top five.
However, Odsonne Edouard and Daniel James' moves earned them plenty of negative reviews, with just 48 percent positive reactions.
This comes as a surprise considering that Ronaldo's return has caused excitement, not only among fans of United but also of other clubs as they want to see how the 36-year-old performs in the Premier League.
