If Lewandowski continues to score just as little, then it is very likely that some "regular" striker from the average team will be able to get around him. 23 goals is not at all the level in modern realities, not only for La Liga, but even for the Premier League, where Kane scores 30 goals in a season and he is still not in first place (because of Haaland).
To begin with, comparing Laliga to the English Premier League is ludicrous; they are profoundly different from one another. Harry Kane and Erling Haaland remained the consistent top goal scorers in england, there energy are unmatchable. Barcelona are progressing gradually, they are getting better with winning clubs in La Liga, yet to improve to the next level. Robert Lewandowski is doing everything he can to adapt to the La Liga style of play. The Poland international has been competitive from the start, and his teammates have been equally encouraging, delivering important assists that have led to goals.
