Igor Thiago signed for the London club from Belgian side Brugge for a club-record fee in July 2024.
More than halfway through the campaign, The Bees are in dreamland.
With victories in five games, and a Brazilian striker banging in the goals, suddenly supporters find themselves drifting off with thoughts of trips to Milan, Munich and Barcelona next season.
A comprehensive three-nil win over the Black Cats moved Keith Andrews' side into fifth in the Premier League – a place that was good enough to secure European football last term.
Solely table-toppers the Gunners have gathered more points over the past half-dozen matches.
There's a long way to go yet but Brentford are firmly in the race for European football.
Few was predicting this last off-season.
The former head coach had departed for Spurs after a seven-year stint in charge, a period in which he had not only got the club to the Premier League but also cemented them in the top flight.
Club captain their Danish midfielder left for Arsenal and goal-scoring duo two key forwards – who scored a combined of thirty-nine goals in 2024-25 – were out the door, joining United and Newcastle United respectively.
Set-piece coach Andrews was promoted to replace the Dane, while there was no striker among the off-season arrivals.
A year of difficulty, possibly even the drop, was forecast. Yet here we are in the new year with Brentford in the top five.
So, what is behind their success?
The club's decision not to sign another striker was in part down to timing, with one forward's move not going through until the final day of the window.
But they also knew they had a £30 million striker already chomping at the bit.
The 24-year-old joined from Belgium in July 2024 for a then club record fee, but was hindered by injury in his debut campaign, going without a goal in his initial outings.
The 24-year-old has gone about making up for lost time this season, though, with his brace against the Wearside club taking him to sixteen league goals – the highest tally by a player from Brazil in a single English top-flight campaign.
Considering the countrymen who have preceded him, that is a remarkable feat, especially with 17 games remaining.
"He's been a breath of fresh air," pundit Danny Murphy said. "He's a physical specimen, quick, strong, but more skilled than people think. Good with his feet, both feet, he can score with both. You can see he's brimming with confidence. His statistics are incredible. He must be so pleased. That's a huge compliment to him."
That only a trio of global superstars have scored more in any of Europe's top five leagues to this point underscores the level he is playing at.
And it is not just the volume but the crucial nature of the goals that have been so pivotal for his team.
His opener against the Black Cats was his 7th opener of the season. Considering how often we are told the significance of the first goal in a game, having someone you can depend on to take that first big chance cannot be underestimated.
Prior to the game against their opponents, no player to have attempted at least thirty efforts this season has a better shooting accuracy than the striker's 59.1 percent.
He finds the target. Achieve that consistently and the goals will – and have – come.
Considering the hardships he had in his youth, where he labored in construction to support his family following the death of his father, perhaps it should be unsurprising that pressure on the pitch is something he handles with ease.
"Our scouts deserve a lot of praise for the kind of players they bring in and characters," Andrews said. "It is really impressive. He is a really unique person who has fitted into life very nicely. He has had to forge this path. He has worked for his journey and toiled. He has got real determination about his personality. He is improving his abilities constantly and we are learning more and more about him. He is a largely all-round centre-forward."
Their star striker is the headline act but the team are not and have never been a single-player team.
While they had key individuals – a host of talent – under their previous boss, they were always seen as a team stronger than the sum of their parts.
The fear was that once the manager left, that may not be the case, and that the sum of their parts alone might not be enough to stay up.
As a result, appointing their set-piece coach, with no previous managerial experience, and just a twelve months at the club was seen by those external observers as a huge risk.
A first managerial job is a test for anyone, let alone when it comes in the Premier League and having made the leap from specialist coach to the top job.
But given that Ipswich Town manager one candidate was the only other alternative that Brentford looked at, they were clearly convinced they had the correct candidate.
So far, as often seems to be the case with the key decision makers at the club, it looks as if they were vindicated.
Andrews won just one of his first 5 league games in charge but big home victories against United, Liverpool and the Magpies have since occurred.
Wins that, following their excellent recent form, could prove increasingly important in the pursuit for European qualification.
"We are in fine fettle and playing really well. We are playing with bravery and belief in everything we do with and without the ball," Andrews added. "We're pleased with how we are going but we want to keep striving."
In a league where fourth and 15th are currently separated by just a handful of points, they have no other option, because things could quickly look very different.
But, for now, The Bees are beating the odds. And the longer that lasts, the closer to fruition those dreams of Europe will become.
