Morton penned a new long-term deal with Liverpool on Thursday and has found himself playing alongside the duo in recent Premier League 2 outings.
Clarkson and Cain both train regularly with the first-team squad and, alongside Morton, the trio were impressive performers during Monday night's 1-1 draw with Everton in the mini-derby.
The latter netted a fantastic goal to earn Lewtas' side a share of the spoils, and attention now turns to today's Premier League 2 meeting with Derby County at the Academy.
Kick-off is 1pm GMT and you can watch the game live on LFCTV and LFCTV GO.
