No, i believe in Kean because i was following him in PSG. He's a good backup option that can deliver 10-15 goals per season and that's what we need from him. As for the future, it's up to him, he's only 22, he might grow into much better player.
Allegri has had 2 years to evaluate his ideas, to give this team something new. Instead, we are stuck with dinosaurball.
