Llorente was good enough because he’s a central striker.
I’d say King’s definitely on a par with Origi. Origi, like King, wouldn’t be a starting player at any top 6 club but as a backup option they’d be very good to have. King has 48 goals in 161 league games for Bournemouth, that’s a respectable record in a poor team. Worth remembering Man Utd had a £20m bid for him rejected in January, we may have a chance of getting him for much less than that.
Gedson isn’t a forward, Lamela is highly unreliable both with form and fitness whilst he could also be a late departure this window, Sessegnon’s positional future is unknown as he may be a LW or LB. Of the players you listed, only Kane is a central striker. It would be suicidal to go yet another season without a second central striker. We saw how much it crippled us last season.
