Daniel Trickett-Smith put the Reds 1-0 up inside 60 seconds but the lads responded well as Michael-Percil levelled midway through the half.
The winger - who levelled so dramatically against Sporting in the NextGen Series last week - then fired the team ahead five minutes into the second half.
However, Trickett-Smith scored again in injury time for the final 2-2 scoreline.
"The first half was in blizzard conditions - the pitch was fine - but we were slow out of the blocks, poor for the first 10 minutes and they scored within about 20 seconds from our kick-off, which was highly disappointing," reported our Academy Manager, John McDermott.
"We got a foothold in the game from there as Harry Winks and Filip Lesniak started to assert themselves in midfield.
"We had a number of good chances with Victor Zapata-Caicedo, whose work ethic and commitment was outstanding and Roman, who took our equaliser really well, a shot across the goalkeeper from the outside right position.
"We started well in the second half and Nathan Oduwa hit the crossbar early on before an excellent counter-attack and cross from Roman that was bundled into the goal for 2-1.
"We lost Harry Winks just after the hour, he's been out recently though injury, the game became a little messier but we had chances to finish the game off.
"Disappointingly, Liverpool equalised with the last kick of the game, from a throw-in and we'd worked so hard that it felt like a defeat driving back down the M6.
"Overall, good performances from Dominic Ball, Alex McQueen was solid, Harry Winks showed good quality and Victor put real energy into the team. He really showcased what he's capable of."
