De Rossi blames Spalletti for the "mess" he created around the retirement of Francesco Totti.
“I was right to say that replacing Spalletti would be difficult," the midfielder said.
“However, I didn't say it was impossible. This has been shown by our journey [under Eusebio Di Francesco], and our the results are there for all to see,
“It seems to me that Di Francesco's first six months have been our best, first six months ever. Even Spalletti didn't do so well on his return.
“Spalletti made a mess last season. As you know, there was a particular atmosphere with Francesco [Totti] and we all suffered a bit.
“Still, I also want to point out the goodness of his work."
