A comeback would be a tall order seeing as the Cherries have never lost a Premier League game while two goals up at the break.
The under-pressure Carrick, who dropped captain Bruno Fernandes for the match, was told he was likely to be out of work come Monday morning.
talkSPORT's Micky Gray said: "Michael Carrick has 45 minutes to save his job."
But chief football correspondent Alex Crook surmised: "This team find new ways to humiliate themselves. I don't think he's got 45 minutes. I think he's done."
Bournemouth at the double
Ayden Heaven gave the ball away with a sloppy pass and then jumped in two-footed with a rash challenge to try and win it back.
He was saved by Evanilson pulling out of the duel, which means Heaven is only given a yellow, but his reprieve was short-lived.
The resulting free-kick was floated to the back post, and Rayan clinically finished past Senne Lammens inside his near post.
The worst was yet to come as Leny Yoro slipped while trying to play the ball on the edge of his own box.

Adrien Truffert ruthlessly punished him by taking over and squaring it for Tavernier to roll into an empty net.
Fernandes dropped
Carrick made the bold call ahead of the match to drop Fernandes following his comments about Man United's tactics in midweek.
The Red Devils were crushed by Como 4-1 in the Champions League, and after the game, the captain questioned the idea not to press the Italian side.
Fernandes then trained as normal on Friday and Saturday before being left on the bench.
Speaking ahead of the match, Carrick revealed that he'd dropped the skipper for footballing reasons.
In his pre-match Sky Sports interview, he said: “Pure football.
"When you have options it's always a difficult decision.
“We have to make the right one for today and the team to get that performance we want."
