As it was my post from another thread that was quoted here's the equivalent combined goals + assists numbers:
Aguero
2014/15 - 34 goals + assists (33 apps)
2015/16 - 26 (30)
2016/17 - 23 (31)
2017/18 - 27 (25)
2018/19 - 29 (33)
Totals: 139 in 152, 0.91 per game
Taken it from 14/15 onwards they're certainly his best 5 years in a row of goalscoring.
Reminder of the other two:
Shearer
1992/93 - 20 goals + assists (21 apps)
1993/94 - 35 (40)
1994/95 - 47 (42)
1995/96 - 38 (35)
1996/97 - 32 (31)
Totals: 172 in 169, 1.02 per game
Henry
2001-02 - 29 goals + assists (33 apps)
2002-03 - 44 (37)
2003-04 - 36 (37)
2004-05 - 39 (32)
2005-06 - 35 (32)
Totals: 183 in 171, 1.07 per game
Might as well do a best-fit equivalent to the other stat I chucked up, the 8 season one when it comes to just goals. It's slightly different for Aguero as he'd not long turned 23 when he came to the Premier League. Can't do ages 22-29 with him like you can with the other two.
Henry's Arsenal PL career 1999/00-2006/07, Age 22-29, 254 appearances. 174 goals, 0.69 goals per game
Shearer 1992/93-1999/00, Age 22-29, 253 appearacnes, 176 goals, 0.70 goals per game
Aguero 2011/12-2018/19, Age 23-30, 239 appearances 164 goals, 0.69 goals per game
