Prade said: "Ranieri's arrival on the bench has been the turning point. Roma are doing great things. We have a great team. Our run continues.
"We conceded the second goal in the 90th minute from a penalty kick. There is a regret. But we had a strong opponent in front of us with great motivations without forgetting that Napoli are now in great athletic condition.
"Under Spalletti the team had lost self-esteem. Ranieri has been very good at involving all 22 players. The club wanted him strongly. He is a very pragmatic coach. He studies the team in a methodical way and makes it work.
