Rodgers told Sky Sports News: "It's a different club and different vision we have here. At Liverpool there's a strategy behind what we are doing.
"We talked a lot with our recruitment team last season, knowing that through the summer we needed to improve the depth of our squad.
"Clearly we were not strong enough last season in terms of numbers and quality.
"We always planned to bring in a number of players, hoping we were going to be in the Champions League, so it would give us the opportunity to challenge on all fronts.
"The new players know their roles and we hope they can develop in the future as well. So far, the integration has been smooth."
