The new season means new players and new shirt numbers. One of them is Randal Kolo Muani. The signing from Nantes has been handed the number 9 shirt, traditionally reserved for centre-forwards and worn last season by Sam Lammers, who has returned to parent club Atalanta. Similarly, Aurélio Buta has inherited the number 24 jersey from fellow right-back Danny da Costa.
