Blackpool, who are heading into another season in League One, provide the challenge behind closed doors at Anfield, with Critchley in charge after leaving his role as under-23s manager in March.
Critchley calls upon two ex-Reds among his midfield ranks, too, with Matty Virtue and Jordan Williams likely to feature against their former club in a warmup tie.
Liverpool will be hoping for a convincing display, as they pick up momentum moving into 2020/21.
