The Seasiders head to the capital off the back of consecutive 1-0 home wins against Hull City and Millwall.
But what team will Critchley pick at Craven Cottage? Here's our predicted line-up...
1. GK - Dan Grimshaw
The keeper will be bidding to keep his third consecutive clean sheet in the league.
2. RB - Jordan Gabriel
Gabriel is likely to come back into the line-up with Dujon Sterling required elsewhere.
3. CB - Marvin Ekpiteta
The skipper will need to be at his best again to deal with Aleksandar Mitrovic.
4. CB - Richard Keogh
Pool will need every bit of Keogh's experience against the free-scoring Cottagers.
5. LB - Dujon Sterling
Without a recognised left-back, the Seasiders will have to be flexible. Sterling could start there having filled in so well last week.
6. CM - Callum Connolly
Ethan Robson will be pushing to start, but Connolly's defensive nous might just give him the edge.
