Rodgers has brought in eight new players this summer, including three in the shape of Mamadou Sakho and Tiago Ilori from Paris Saint-Germain and Sporting Lisbon respectively and Victor Moses on loan from Chelsea on deadline day.
The Anfield chief believes the Reds' summer dealings have added competition to the squad and he has a hungry new-look squad at his disposal.
"I'm obviously very pleased," said Rodgers. "The window this summer has been very productive for us.
"We've certainly got more competition and as a manager you always want more, but we're more than happy with the business we've done.
"We've added freshness to the group. What we were looking to bring in was hunger - even though Kolo Toure is 32, he's very hungry to succeed.
"We've done great business over the course of the summer - and we'll run with that until January and see where we're at then.
"I'm sure we'll look to strengthen again and finish off the second part of the season like we did last season."
