The Blues head coach has opted for the on-loan Manchester City and Republic of Ireland stopper – despite his understudy’s man-of-the-match display at Wycombe last week.
Bazunu is one of two changes to the side that beat the Chairboys 1-0, with Michael Jacobs recalled at Miguel Azeez’s expense.
And while many supporters on Twitter agree with Cowley’s goalkeeper call, there’s plenty of sympathy out there for Bass,
Here’s a selection of the views shared on the social media platform following the unveiling of today’s team sheet...
@Ben_Kumma: Hard on Bass but Bazunu will be a Premier League keeper within the next year or so. Gotta pick the best player!
@84Knight: Harsh on Bass, but probably the right call.
You should always play your best players/team even if an understudy has had a good game.
@SamGudge: Bass doesn't deserve to be dropped but good to see Jacobs back.
@MikeTattooed: Bass should be in goal today.
Yes Bazunu did well at international level ,but Bass is a #Pompey player.
He is OURS so he should get the nod on a 50/50.
To keep developing someone else's player when your own player pulls off an amazing display does not sit well.
@colinlbrown: Surely Bass wasn't dropped, he was covering whilst Baz was away?
It's what backup/squad players do…
@philhayman2: Harsh on Bass that.
@pompey0: Only disagree with Bazunu. Bass should have started! However, Play up Pompey!
@LeeCrowhurst: Got to feel sorry for Bass. That was a very harsh decision!
@RoryJones_: Gutted for Bass, don’t know what sort of signal that sends out.
Should be nurturing our own players.
@Darryl30804467: I’d rather a keeper that keeps clean sheets than can play with his feet.
