Lifted from a blue's post on PepCafe.
How does that compare with Shearer & Rooney to get to 200?
Using their respective time in the premier league as a guide its Aguero by about 100 games.:
Shearer got 205 in 392 appearance for Southampton, Blackburn and his first couple of seasons at Newcastle.
Rooney got 198 in 442 appearances for Everton and United, he broke 200 in the season where he had 214 after 479 games.
Aguero has 201 in 292 games for City, so if he gets 4 in his next 100 appearances he'll better Shearer.
But to put things in perspective, Aguero arrived in England at 23 (maybe 22) the others started as teens.
In terms of career totals:
Aguero has 325 goals in 582 appearances. Sergio has scored in 56% of matches he's played.
Rooney has 282 goals in 680 appearances. Rooney 41% of matches.
Shearer has 379 goals in 734 appearances. Shearer has goals in 52% of games played.
Shearer is 16th in the premier leagues all time goal per minute standings (every 147 minutes).
Rooney is not on the list.
Aguero is 1st, (every 107 minutes) ahead of even Salah of all people (Salah's record being ruined by 2 goals in 9 hours for Chelsea. .)***
***Was correct at the newest article I could find (March 2018), but I suspect Salah (109 min) and possibly Kane (113 min) may have passed Sergio towards the seasons end.
One things for sure, had Kun not those dodgy hamstrings, he'd possibly be have a chance at touching 500 career goals now. (40 for Argentina in 89 appearances).
