Donati signed with the Apulia club in January after six years away from Italian football.
Asked to describe the former central midfielder's coaching style, Donati told Tribalfootball.com: "As for Liverani, he made an excellent impression to me, for his personality and also for what he asks because he is a coach who never gives up playing, despite being a newly promoted team with surely many technical problems also compared to the others teams.
"Because otherwise we will be in a worst position in the standings. Despite this difference of quality with many opponents, he never asks us to throw the ball away to do catenaccio, but always to try to get out from the box with the ball, to play, to change the game. So, he is a pleasant coach for the wingers and the players who are wide on the pitch."
Compared with other managers in his career, Donati added: "It would be difficult to compare him to someone, perhaps to Davis Mangia in the sense of a young trainer with a lot of personality and, above all, many pretensions. I like him because he is a coach who requires a lot from the players because he believes in it, therefore he proves to trust his players, therefore very demanding and precisely with a very positive idea of the game."
Other than the management of Liverani, Donati says he was convinced to sign with the club due to the pull of the city and their supporters.
"Having spoken with the coach, seeing that it is a lively, determined team. Then, the fact that I've already been here, that I know the city, enthusiasm that there is towards the team from the fans, by people even outside the world of football. It's a wonderful place and I'm delighted to be back!"
Lecce are currently 16th and three points clear of the relegation zone after 24 matches.
And Donati thinks the club will work tirelessly to avoid the dreaded drop.
"I can't tell you how many chances we have, but surely the desire and enthusiasm that we put into it every time we train it is very high. We have to struggle hard, even because the league table is very short, will try to give our best, game after game, in order to achieve this goal which would be fantastic."
