The important records ( most goals in a season and most goals in a calender year ) are out of his reach. He never even came close to Messi's 73 and 91 even at his absolute peak. And he isn't going to do it now.
Most European Golden boots: he trails Messi by two. And he looks unlikely to add any.
Most domestic top scorer awards: trails Messi. And he's not going to close the gap, nevermind catch up.
Highest scoring average : trails his contemporary Messi, nevermind surpassing Muller and co.
He can keep trying, but it's unlikely that get the important records.
With regards to the thread topic (which you seem to have divagated from with random cumulative totals that have no relevance to the topic on hand), he's going to need to score more than 45 a season if he indeed plays 3 seasons here. The last time he managed to reach 45 goals was 6 seasons ago. He hasn't even hit 40 in a season his his Madrid days.
It's unlikely that he'll do it.
True most goals in a season belongs to Messi, its a big record. But those other records you mentioned are not really that important in my opinion, they are one of those records where no one really cares or talk about, and you can't easily find anyone mentioning or discussing those from the internet, nor can you find those from Wiki.
In my opinion, the biggest records are: (in no particular order, mainly due to prestige, popularity or with most media coverage, in relative to records in biggest stage/highest level)
- Most career goals - Ronaldo
- Most international goals - Ronaldo
- Most CL goals - Ronaldo
- Most WC goals - Klose
- Most Euro goals - Ronaldo
- Most goals in a season - Messi
Then we also have other big records related to individual awards/honours/trophies:
- Most Ballon D'or - Messi
- Most Golden Shoe - Messi
- Most WC winner - Pele
- Most CL winner - Ronaldo
Followed by that we also have a big big list of other records, such as most goals in particular league, most goals for particular club, most international goals for particular continent, most international goals for particular country, most assists, most goals in Euro/WC qualifier, most goals for single club, most goals in particularly competitions, most top scorer in particularly domestic competitors, most motm, most consecutive game on scoring goals in domestic league etc the lists are endless. But I don't think they are anywhere as important as the ones listed above, at least not in a traditional sense.
What I mean here is, there's not many big records left he could break, as those within his reach he has already broke them all, with exceptions of few such as most WC goals, most goals in a season, most WC winner, most Ballon D'or etc which I don't think its within his reach now. So the only realistic one left for him is to break more club records for Man Utd. I think even if its unlikely he could break Rooney record in the end, this may still motivates him to score more more goals for us, as he always strives for more records.
