The Brazilian has recently completed a successful loan stint with SJK.
Unfortunately the player is not yet eligible for a work permit to play in the United Kingdom so he was sent out on loan to the Finnish outfit Seinajoen Jalkapallokerho, or SJK for short, in September.
He had a productive time playing in the Veikkausliga, Finland's top-flight, and SJK were crowned champions for the first time in their history last month.
Now, after a little break, it seems the 18-year-old is back in first-team training with Liverpool at Melwood.
He was pictured in action with his compatriot Philippe Coutinho and forgotten left-back Jose Enrique in training yesterday as Liverpool prepare to take on Manchester City at the weekend.
Whether or not he is now eligible for that game is not known but it is doubtful he would be thrown in at the deep end just yet regardless.
It is expected that Allan will be on the move again soon with another loan deal likely to improve his development.
