De Rossi was axed by Zeman on the weekend.
"A guy like that cannot be lost, especially in a Roma made of many young players," Lanna told TMW. "I would try, if I was them, to rebuild the relationship and especially to make sure that things do not come out in the press, disputes cannot keep appearing in the newspapers in a society like Rome.
"Roma has just made a major contract with De Rossi but is that the case of protecting the player or really the risk of losing him? The statements emerging are heavy and also seem out of place."
