plenty of slightly above average players like Jermaine defoe, darren bent managed to score 20 pl goals in one-off season too tho.
With the new penalty rule, the rat face diver will manage it too, despite having only scored 7 non-penalty goals so far.
Anyway, I think Werner this season is a one off adn i can see him score 15-20 pl goals next season. Havertz i can not really say cos he used to blow hot and cold even in bundesliga. The thing is, to make the best of werner we need to play more on the counter attack and less posession based. can not really see this under tuchel so far, so it is likely we sign another player who is more suited to leading the line vs deep sitting teams.
