Chiesa had an absolutely amazing second half of the season under Pirlo in 2020/21. His numbers from January to June 2021 weren't that magnificent (9G/6A), but he was simply unplayable. He continued his great form at the EURO in 2021.
Ever since we are waiting for him to be that unplayable Chiesa from 2021, but it never happened. Injury or not, half a season in 4 years is way too little for a superstar status.
I won't mind at all if he leaves, because he's far from irreplaceable.
