Rodgers believes the Reds will benefit from having a "£50-£60million" striker back in the side and the timing is perfect as they face arch-rivals Manchester United in the Capital One Cup at Old Trafford on Wednesday night.
"Now he comes back we are getting a £50-60million striker back in the team and that is exciting for us," Rodgers told talkSPORT.
"This is a player who can come in and make a difference for us."
Liverpool, of course, turned down a now infamous £40,000,001 bid from Arsenal in the summer as the Uruguay international tried to manufacture a move away by claiming his manager and the club reneged on a deal to allow him to move to a Champions League side.
Rodgers insists that is now firmly in the past but he accepts Suarez may have some convincing to do in the eyes of some fans who felt he betrayed the club with his comments in the close season.
"All you can do now is judge him by his performances on the field. The measure for Luis now is on the field," he added.
"His way to say sorry or make any contribution back to the supporters is to play with his heart 100 per cent and score goals and make this team successful and I am confident that will happen.
"He can't play any other way."
Rodgers is confident his players will bounce back quickly from their poor performance at Anfield which resulted in surprise defeat - their first since March - to Saints.
"There's no doubt after Southampton at the weekend, we haven't felt like that for a long time. It was hard to swallow," he added.
"We didn't perform and it's as simple as that. We were nowhere near our level.
"That's going to be the season - sometimes it's going to be up and down. All we can ever do is work hard and keep believing.
"We're back focused, working hard and knowing this is a season where we'll have those ups and downs.
"We've just got to make sure, like we have done, when we have a disappointment we bounce back and go again."
