Obviously Ronaldo and Messi are up there with Pele and Maradonna. But for some reason despite their goals I don't see them as 'proper' strikers. I know the game has changed. Its like those two are in a league and positions of their own!

Shevchenko for example was the best in the world for some time. People often overlook the fact he won the Balon D'or. But he gets forgotten because of his poor spell at Chelsea (Like Torres, Falcao and to a lesser extent Eto'o.). But his time at Dynamo Kiev (twice) and AC Milan show he was great.
Shearer, Batistuta, Van Nistelrooy, Romario were what I would call 'proper' strikers. And have to be up there. Henry and Ronaldo Mk1 were geniuses. And probably most close in style to Messi and Ronaldo of today.
David Villa another who was unbelievable at Barcelona but outshone by Messi as Benzema is with Ronaldo.
Zlatan a genius but like Ronaldo mk1 incredibly never won the champions league.
Klose rarely gets mentioned but has a phenomenal record individually and as a team player. Nobody will even consider Rooney but hard to overlook what he achieved.
Plenty of other Serie A Players I loved watching in the 90 and early 2000s - Weah, Klinsman, Crespo, Vieiri, Del Piero, Baggio.
Any I have missed?
If I had to pick one player from that generation to play for Burnley I would pick Ronaldo the original. Had everything - pace, strength, finishing, heading, skill and but for his injuries would have been the best player of all time.
