I think if he went to England or Spain or even Italy, he would get more exposure/pr.
In fairness, Bundesliga is by far the most player friendly league. Schedule is good, less games etc. A level below Liga and EPL at least in terms of physicality.
Players like Robber and Ribery benefited a lot from that.
Make a statistic comparison of domestic games and minutes among top strikers in England and Spain to compare him with (past 5 years):
Suarez - 203 Games - 17.153 Minutes
Lewandowski - 200 Ganes - 16.762 Minutes
Kane - 199 Games - 16.453 Minutes
Aguero - 186 Games - 16.453 Minutes
Benzema - 176 Games - 13.274 Minutes
This means Lewandowski hasn't been exposed to lesser minutes than any other forward in domestic games bar Suarez. Which makes a lot of sense, remember Bayern never really had a serious backup for him. He is Plan A and there has never been Plan B.
Now add International games and NT games to that aswell.
Suarez - 53 int Games for Barca - 4.711 Minutes - 31 Games for Uruguay - 2.724 Minutes
Lewandowski -55 int games for Bayern - 4.606 Minutes - 49 Games for Poland - 3.916 Minutes
Kane - 40 int. Games for Tottenham - 3.048 Minutes - 43 Games for England - 3.336 Minutes
Aguero - 39 int. Games for City - 2.925 Minutes - 40 Games for Argentina - 2.291 Minutes
Benzema - 63 int. Games for Madrid - 4.747 Minutes - 10 Games for France (before kicked out) - 598 Minutes
This makes a grand total of minutes and games played since 2014:
1. Lewandowski - 304 Games - 25.284 Minutes
2. Suarez - 287 Games - 24.588 Minutes
3. Kane - 282 Games - 22.837 Minutes
4. Aguero - 265 Games - 19.470 Minutes
5. Benzema - 249 Games - 18.617 Minutes
Now the injury list in all these 5 years:
Lewandowski injured for 11 games, longest time ever injured: 2 weeks
Suarez injured for 15 games, longest time ever injured : 5 weeks
Kane injured for 35 games, longest time ever injured: 7 weeks
Aguero injured for 38 games, longest time ever injured: 6 weeks
Benzema injured for 39 games, longest time ever injured: 6 weeks
He is by far the most overplayed forward around bar Ronaldo AND he is injured practically never.
His injury list consists of simple knocks and bone injuries, almost not a single muscle injurys over the entirety of an entire career.
AND he is 31 and
still in prime. That is both a mixture of freak genetics and Ronaldo levels of taking care of yourself.
