Goals from James Norris, Harvey Blair and Isaac Mabaya helped the young Reds end 2020 in the best way possible.
Norris opened the scoring from the penalty spot after 25 minutes before the hosts equalised through Bartosz Cybulski on the stroke of half-time.
But Marc Bridge-Wilkinson's team quickly regained the lead early in the second half with Blair's finish as Mabaya then made sure of the win with his 54th-minute strike.

Speaking to Liverpoolfc.com post-match, Bridge-Wilkinson said: "It was a nice way to end the year with a hard-fought win, I would say.
"The pitch was very lively and slippy with a strong wind. It was a different type of performance but I was pleased with the way the boys dug out the win.”
