"It's only been positive" since Spaniard left
Comolli suggested the Spaniard’s desire to move away from the club had a negative impact on the team and performances on the pitch.
Torres's disenchantment led to him handing in a transfer request late in the January transfer window before pushing through a British-record £50 million move to Chelsea.
Money Liverpool gained from the transfer was used to bring in Newcastle United striker Andy Carroll, with Ajax ace Luis Suarez also sealing his protracted move to Anfield on the final day of the window.
Comolli believes that the sale of Torres and the deadline day signings have improved the morale within the club.
He told the club's official website: "As I said, when you have someone who doesn't want to be here and you swap him for people who want to be here the atmosphere changes.
"It's like there is a bright new sky with no cloud over our head from the day that happened. So it's been only positive."
Comolli has also insisted he expects the club to be active in the transfer market during the summer.
He continued: "The owners said from day one they want to improve things and turn things around quickly and I have said the same thing since I arrived. So I expect a busy summer."
Comolli believes the business of looking for fresh new talent does not cease despite the close of the window and explained that the club continues to search for talented prospects during the whole season.
"When we prepare for the next season it's difficult to say we work to the January transfer window," he said.
"We work from summer to summer, when the window shuts in September we are preparing for the next summer window, not the one in January because, as people say, usually not much goes on in January.
"We proved that wrong, as soon as it shuts on January 31 we are thinking about the summer and what we are going to do.
"We talk about different targets, about players we thought about in January but couldn't do and keep the scouting team working."
