When Brentford and Sunderland met at Griffin Park last month, the Bees had won only once at home all season; the visitors raced into a 3-1 lead.
But Brentford responded to earn a draw and, against Leeds United on Saturday, won their next home match.
Dean Smith's side have very much turned their season around, collecting 19 points in a nine-game unbeaten run to climb up to 12th.
Prior to that streak, the Bees had just three points from seven games and sat in the bottom three. They must be Sunderland's inspiration.
While a nine-game unbeaten run - including five wins - seems impossible right now for the Black Cats, who headed into Sunday's Tees-Wear derby bottom of the table, they surely boast a better squad than Brentford.
There are many cliches mentioned when discussing the Championship, but Brentford have shown that a series of positive results can turn a season around.
Sunderland - like the London club were - are on a torrid home run and that must be the first step on the road to recovery.
If the Black Cats appoint the right manager and beat Millwall at the Stadium of Light in their next game, they have to believe they can pull clear of danger - just as Brentford have.
