His scoring record is genuinely excellent. 45 goals in 92 x 90s. Virtually one in every two games, made all the more difficult playing for a mid/low table side and also not being a first choice starter for two and a half seasons.
Only Salah scored more non-penalty goals than him last season, and he drew for non-penalty goals scored with Isak and Haaland, who I believe cost a tad more than the £8m Wissa did
I can't understand why anyone wouldn't want to sign him, but I can understand not wanting to sign him for the likely £50m we'll ask for. He's 29 soon. You'd get lots of goals from him, but that money could be spent on someone younger.
