NAPOLI star Giacomo Raspadori insists they have not even reached top form despite annihilating Ajax in a chilling warning for Rangers.
Rangers have still got to go to Italy to play a rampant Napoli side who have now scored 13 goals in just three games after thumping wins over Liverpool, Rangers and Ajax, who were destroyed 6-1 in Amsterdam.
Giovanni van Bronckhorst's side travel to Naples in three weeks and face a daunting challenge against the Serie A winners.
But Napoli and Italy striker Raspadori, who scored twice in the Johan Cruyff ArenA reckons they can get even better ahead of playing Rangers.
He said: "The secret of Napoli is the strength of the squad.
"I think the most important thing is this team continues to grow every week and gets stronger.
"We can definitely still improve and I think there is more to come from us.
"This was a great match against a good team in Ajax. But we have to think we have not reached our best. There are still things that we could have done better.
"We all have the desire and enthusiasm to improve.
"I think you have to credit the manager. He gives all of us so much confidence. When I came here he made it clear he wanted to sign me at all costs and he has helped me show my qualities.
"But the truth is, I am only playing well just now because of the strength of this team. They are the ones who are helping me and I think I am gaining more confidence with each passing game.
"We have to concentrate on the next game now at the weekend and forget about this one."
