Bonazzoli is young but still has good Serie A experience. I think he can be considered a sharpshooter reminds me of Ventola when Inter first bought him, he has good pace and good at heading too. Bonazzoli helped save Reggina from relegation after joining them in January (winter transfer) and I think scored 5-6 goals.
Muzzi is far more experienced, sort of a Signori. But Muzzi is slower and not that good at heading, he has a strong shot and is good at taking penalties.
I can't judge Yanagisawa as I haven't seen him play except for the friendly against us.
