"[Luciano] Spalletti 'invented' Totti as a centre-forward when he was left without any other available strikers," explained Ranieri.
"By introducing all those midfielders who moved up without the ball, he represented an innovation in European football.
"However, Totti has to change his style of playing. Even rocks know how he plays now, that he comes back to get the ball. He needs to make different movements.
"For now I am just asking him to do what he knows best, with the ability to read the game. I gave him a lot of advice, respecting his quality as a huge champion."
