Cavani has 8 in the league.
Lingard has scored 9. So have Barnes, Zaha, Mahrez, Sterling, and Aubameyang.
13 players have scored more goals than Cavani, 8 additional have scored the same number.
Of the forwards, Cavani is level with Jesus, Iheanacho, Maupay. Of the midfielders, he's level with Bowen, Pereira, Jota, Mane, and Maddison.
If that equals superstar to you, then so be it. Cavani is past his best even if he scores some dramatic goals for us. This is no discredit to Cavani; I like him, he's just not one for the future. We still need a young, hungry forward to take us to the next level (or get us back to where we belong). Cavani has been a good stopgap measure, an upgrade on the previous stopgap Ighalo.
