Pretty much 14/15 was Suarez only real world class season in the Champions League, although he was a clinical finisher in 15/16 too.
Quite a lot of his prime years until he went to Barca were spent in the Europa League.
Its getting increasingly more difficult to put him above Lewandowski as the best striker of that generation.
Sure, Suarez had a higher peak, but Lewandowski has the consistency, and his record in the CL is much better than Suarez now.
Suarez of 2010-2017 was much better than Lewy ever was or will be. Remember his Ajax and Liverpool years as well as his heroics with Uruguay. Uruguay was in the final four at the 2010 World Cup and won Copa America in 2011. Lewy has great stats but if you take a closer look at his game and contributions, he is not as complete as people make him out to believe.
