His six England players and new signing Fabio Borini sat out Wednesday’s 2-1 defeat to Roma at Fenway Park having joined the squad just this week.
“We’ve got a tough session in the morning for the players who have just arrived,” Rodgers told reporters after the Roma defeat.
“In the next couple of days we’ll assess it. There are certainly going to be some of those guys involved. It’s thinking towards the Europa League game next week.
“A number of those guys will come in and start to get involved.”
One player who did feature against Roma is Alberto Aquilani, currently with the squad after two full seasons on loan in Serie A.
Asked whether he would remain at Liverpool during 2012-13, Rodgers replied, “That remains to be seen. I need to have a close look at Alberto. It’s been difficult for him during his time in England, and this is probably the first period where he’s felt happy, according to him, and he’s working.
“I need to assess, and that’s what I’m doing at the moment. Come the beginning of the season I hope to have a group that I’d like to go forward with on our journey this season. I’m assessing all the players, young and senior, at the moment.”
Meanwhile, despite losing our latest friendly 2-1, Rodgers took many positives from the game.
He praised the build-up to Charlie Adam‘s strike, which followed goals from Michael Bradley and Alessandro Florenzi.
The boss also had kind words to say about Lucas Leiva and his side’s tactical approach to the game.
“I was really pleased with tonight,” he said. “There were lots of real positives from the game. Roma are ahead of us in terms of games — they’ve played four or five more than ourselves.
“We actually created a lot of chances, and once we get that wee bit fitter and introduce our top players, I’ll be very hopeful for the future.
“The pressing from the front was very, very good, the goal we scored was excellent, and we’ll improve our defending from the goals. We defended poorly on those.
“It was a well worked goal. We showed patience and moved it quickly from one side of the pitch to the other. Daniel Pacheco played a great ball when I thought he was going to work space to shoot. It was a perfect pass so Charlie could hit it first time.
“The structure of our game was good. That’s important for me at the moment, that tactical idea, because when we introduce a lot of our quality players back into the group you’ll see that extra step up in the midfield and final third.
“I thought Lucas was fantastic when he came on. Some of his passing and quality.
“There were also lots of young players gaining invaluable experience against top players like Bojan and Totti. That’s going to help them going forward.
“Young Ryan McLaughlin playing at right-back, his first game, a fantastic experience for him playing against Totti, a legend of the game.”
The Reds will depart Boston for Baltimore on Friday morning — and Rodgers believes his players will never forget the day they played in front of a capacity 37,000 fans at the home of the Boston Red Sox.
“It was incredible,” he said. “I’d like to go on record to say a big thank-you to the people of Boston. We’ve got one more day here before we fly away on Friday, and it’s been absolutely magnificent.
“The hospitality we’ve received here, and to climax it by playing at an incredible stadium…
“I told the players before the game, ‘When you’re 50-odd you’ll be able to tell your grandkids that you played football at Fenway Park.’ That’s something that’ll stay with them.”
