I really think that we should be looking in the Bundesliga for a striker, not France.
The pace is similar to the Prem and most players from Germany seem to have it easier when it comes to adapting to the league because of that.
Someone like Weghorst at Wolfsburg (tall, strong target man), Quaison at Mainz (similar to Kane in size and build, bit pacier), Andersson at Union Berlin (again a target man in the Llorente mold) or Plea at Gladbach (similar to Kane and Quaison in size). Either of those four I think would complement our attack well.
Quaison has a rocket hidden in his boot from time to time as well.
