Johnson has spent the week with the club's youngsters after being overlooked for England this week.
"It is strange for me as I've not been too used to it - I'm normally away," Johnson told Liverpoolfc.com.
"It's different. I'm training with the Academy lads and some players who I've never met before. It's good and it's different - of course, I'd rather be away on international duty.
"But we've got some fantastic players and it's good to see that. It's good for them to step up and train with some members of the first team. It's a different situation, but it's good for everyone."
