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...
7. CM - Kenny Dougall
Thankfully the Aussie wasn't called up for international duty, otherwise the Seasiders really would have been in trouble.
8. RW - Josh Bowler
The winger is in great form and scored the winner in the first fixture at Bloomfield Road in September.
9. LW - CJ Hamilton
Charlie Kirk will be hoping to make his debut and Owen Dale will also be pushing to start, but we think Neil Critchley will keep faith with CJ.
10. ST - Shayne Lavery
The striker will be aiming to get in the goals again after his match-winning strike last week.
11. ST - Gary Madine
The striker has been in impressive form recently.
