But then no one at Stockley Park could bail the Yorkshire-based official out in his latest Premier League fixture either.
Barrott has been handed the middle for the Seagulls' Carabao Cup clash at Arsenal.
VAR will not be in operation, even though it is an all-Prem tie taking place at a top-flight stadium.
Barrott was in charge at Bournemouth on Sunday where he, perhaps understandably, awarded the home side a corner against Nottingham Forest having not noticed a double ricochet.
The Cherries scored from the flag kick on the way to a 2-0 win.
VAR cannot intervene in such incidents although there were renewed calls for that to change.
Barrott was praised after he played advantage ahead of the second goal.
Bournemouth boss Andoni Iraola said: “Sometimes they give you advantage because you still are on the ball. But it's not advantage because the free kick was more valuable without your position.
“But I think he has got it right.”
Albion fans last saw Barrott on the opening day of the season, when he awarded a penalty which was converted by Matt O’Riley.
Fulham went on to salvage a 1-1 draw just before full-time.
He also did their home game with Fulham last season, when Joao Pedro scored from a very late spot kick.
So far this season, across all competitions he has refereed seven games and shown 37 yellow cards as well as one red, to Reinildo of Sunderland.
He showed yellow 133 times and red just once last season in 28 fixtures.
Wade Smith and Akil Howson will be on the touchlines at the Emirates with James Linington acting as fourth official.
