I don't mind Jesus being there so that as Gyökeres tires he's an option. Thought Gyök was a mite unlucky not to score today too. As was Saka.
From what I recall, as I was a younger man the last time Havertz was uninjured for a month, Havertz was quite a bit more effective than Gyök when fit.
Havertz is quite a lot better in the aerial duels, and also better with ball at feet. He's still far from an ideal striker but I'm keen to see him back in action. It feels to me like we're inches away from scoring loads of goals at the moment.
