The 17-year-old goalkeeper joined the Reds last summer from Legia Warsaw in his native Poland.
He immediately joined the first-team travelling party for the summer tour of the USA.
Kuba – as he is known to all at the Academy – linked up with the club’s U18 squad once he gained his international clearance in September.
One of his season highlights was a number of fine early saves in the U18s derby with Everton, which the young Reds went on to dominate and win 6-1.
The Polish youth international is a fine shot-stopper and has been developing his distribution with the ball at his feet during his first term at the club.
