I think if he keeps all his main players and has a relatively injury free season he’ll challenge for the PL or CL, yeah.
I very much believe in Conte as a manager. He doesn’t go places to feck about and ‘rebuild’, he goes in to win. He’s a winner.
Look at the posts here when he took over Spuds regarding them getting Top 4, and how did that turn out?
He isn’t a guy that’ll be trying to achieve the minimum to cling on to his job and buy more time. He’s a ruthless trophy hunter, and now has a forward line of Kane, Son, Rich, Kulu…
It’s easily good enough to win a big trophy, and so is Conte.
