He wasn’t though ? We won more with Ronaldo than Eric. Ronaldo had a 42 goal season in which we won the league and CL, where he scored goals that earned us 21 points alone, he won four United Player of the years, three premier league player of the years, the balon dor. We won the league three times in a row for only the second time in our history, the CL for only the third time, the world club cup , two league cups and an FA Cup in which Ronaldo was outstanding and scored the opener in the final. He was as talismanic as Cantona and more successful. He was a far better player in addition.
It's great that Ronaldo scored 42 goals in a season and it's great you keep mentioning it but it's not relevant to this discussion because;
1) a goal alone doesn't equal a memorable or standout/important moment.
2) Ronaldo was the main attacking outlet for the team during that season, Cantona was a second striker. Goals weren't the only thing he did, as shown by him being top assister in the league twice. Comparison of goals scored is useless. Which is good because this was about player impact for the entire team.
You're right that Ronaldo scored a shit load of goals during our League and CL season, the CL being the one thing Ronaldo has over Cantona from a team perspective (since I as a United fan am looking for United moments and not how many Balloon Doors a player has to their name). Being a better player also doesn't mean they provided better moments. They're two completely different identifiers. Pure moments are subjective and depend on how much you actually saw both play. But since you're focused on numbers let's start with those...
Worth pointing out that Ronaldo has three league titles, Cantona four, and Ronaldo has one FA Cup, Cantona two.
Cantona also scored more match winners than Ronaldo. 16 match winning goals for United compared to 13 for Ronnie. A reminder again that Cantona was a second striker and played less seasons than Ronaldo.
Even ignoring anecdotal opinions and memories from people who actually saw both of them perform and sticking to the raw numbers doesn't do much for Ronaldo at United.
But the CL, the club honour Ronaldo has that Cantona doesn't. I remember it well. I remember his great header in the first half, and a couple of crosses before he became invisible for the rest of the game - barely got into the box and jogged around. Then he bottled his penalty. If Terry hadn't slipped we would have lost that game. Van Der Sar won Man of the Match.
To say Ronaldo was more talismanic than Cantona is just bizarre.
