Liverpool academy chief John McParland says the NextGen series has been great for his players.
Liverpool continue this season's campaign today against Inter Milan.
McParland told liverpoolfc.com: "I guess we're victims of our own success in many ways. The NextGen has been brilliant in helping to bridge that gap between youth and senior football. It's been massive for their development.
"The likes of Conor [Coady], Andre [Wisdom], Suso and Adam [Morgan] benefited a lot from playing for us in it last season. That experience of European away trips with the travel and all the preparation will stand them in good stead this week.
"As well as missing those lads, obviously we're also without Raheem Sterling, Jon Flanagan and Jack Robinson, who have already made the step up.
"Raheem is actually eligible to play in the NextGen for the next two seasons but he's done so well he's a first-team regular now."
