Roma have lost three of their last five games.
"Totti has recovered and can play from the start, which is lucky for us. Can Totti play alongside Erik Lamela? All situations are possible. Totti played many times as a centre-forward, though I think his natural position is trequartista.
"Do I have a basic Roma team? There are four or five players who more or less play all the time, plus others who rotate.
"The players must get used to what I am asking for and not just know what I want, but how they have to do it. There are important details we still haven't finalised yet.
"I expect a difficult game and if we don't show a hunger for success, then we'll suffer a great deal. Lecce have interesting and dangerous players like Cuadrado, Carlos Grossmuller, Ruben Olivera and Andrea Bertolacci.
"I expect three points against Lecce if we all give 100 per cent. If we don't, then Lecce can win at the Olimpico. We are not one of those teams who can give 50 per cent and still win. If we don't keep possession, attack space with vertical passes and mark our opponents, then of course Lecce can win."
