I'm not crying about him, but he was the standout player in a relegated team, which is a big achievement if he played well against better opponents every game. Goals, assists, and leading the team despite being surrounded by weaker players.
Can we compare it with other standout players in the relegated teams from the last 5 seasons?
This year Soule had 11G/3A season in 3141 minutes. That's a little better than Pinamonti (25 years old) from the relegated Sassuolo who had 11/1 in 3100 minutes and Candreva (37 years old) with 6G/6A in relegated Salernitana.
In the previous 5 seasons the best players in the relegated teams:
1. Simy (29 years old; Crotone) in 2020-21 had 20G/2A
2. Caputo (31 years old; Empoli) in 2018-19 had 16G/3A
3. Joao Pedro (30 years old; Cagliari) in 2021-22 had 13G/4A
4. Mancosu (31 years old; Lecce) in 2019-20 had 14G/2A
5. Nzola (26 years old; Spezia) in 2022-23 had 13G/2A
6. Junior Mesias (29 years old; Crotone) in 2020-21 had 9G/4A
7. Petagna (25 years old; SPAL) in 2019-20 had 12G/1A
8. Krunic (25 years old; Empoli) in 2018-19 had 5G/7A
9. Aramu (27 years old; Venezia) in 2021-22 had 7G/5A
Soule is (much) younger than all of them, so he gets points for potential, but the theory that being the standout player in a relegated team is some big achievement does not stand IMO, because none of the guys above did something wow after their teams got relegated.
