Keane had a difficult first season with Everton, but grew into a key player last term.
The England international has started this season where he left off, as Keane was superb in Everton’s first game.
The Toffees picked up a 0-0 draw against Crystal Palace, with Keane looking hugely impressive.
And Coleman said: "Michael was different class all last season and throughout pre-season and has really grown into an Everton player.
“His first season was difficult for everyone and he had to battle through that, which he did excellently.
“You can see his confidence and how he is playing with his chest out.”
Keane has a different partner at the back at Everton now, as the Toffees failed to get Kurt Zouma back.
Zouma and Keane formed a great duo in Marco Silva’s defence last term, but Chelsea decided to keep the Frenchman this time around.
Yerry Mina has been promoted to start in Everton’s defence this term, and the signs were promising at Selhurst Park.
Everton are next in action against Watford at the weekend.
