Igor Thiago signed for the London club from Club Brugge for a club-record fee in July 2024.
More than the midpoint of the season, The Bees find themselves in fantasy land.
With four wins in their last five outings, and a Samba striker scoring the goals, suddenly Bees fans are dreaming of thoughts of trips to Milan, Munich and Barcelona next season.
A emphatic 3-0 win over the Black Cats moved their manager's side into fifth in the Premier League – a place that was good enough to secure European football last term.
Only 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 squarely in the battle for continental football.
Few was forecasting this last off-season.
The former head coach had left for Tottenham after a seven-year stint in charge, a period in which he had not only guided the club promoted but also cemented them in the elite division.
Club captain their Danish midfielder left for the North London club and goal-scoring duo two key forwards – who scored a total of thirty-nine goals in 2024-25 – were also sold, joining United and Newcastle United respectively.
Specialist coach Keith Andrews was promoted to succeed the Dane, while there was no striker among the summer signings.
A year of struggle, possibly even the drop, was forecast. But here we are in January with Brentford in the upper echelons.
So, how have they managed it?
The club's decision not to sign another striker was in part down to circumstance, 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 ready and waiting.
The 24-year-old joined from Club Brugge in the summer for a then-record fee, but was plagued by fitness issues in his first campaign, going goalless in his initial outings.
The 24-year-old has gone about making up for lost time this season, though, with his double against the Wearside club taking him to sixteen league goals – the most by a player from Brazil in a single Premier League campaign.
Considering the fellow Brazilians who have come before him, that is a remarkable feat, especially with seventeen matches remaining.
"He has been a breath of fresh air," pundit Danny Murphy said. "He is a physical specimen, quick, powerful, but more skilled than people think. Excellent with his feet, either foot, he can score off both. You can see he's full of confidence. These numbers are fantastic. He must be so pleased. That's a big compliment to him."
That only a trio of global superstars have scored more in any of the continent's major leagues to this point shows the level he is playing at.
And it is not just the quantity but the crucial nature of the goals that have been so vital for his team.
His first goal against the opposition was his 7th opener of the season. Given how often we are told the importance of the initial strike in a game, having someone you can rely on to take that early opportunity cannot be overstated.
Prior to the game against their opponents, no player to have attempted at least 30 shots this season has a better shot accuracy rate than the striker's 59.1 percent.
He hits the target. Achieve that consistently and the goals will – and have – come.
Considering the hardships he had in his youth, where he worked as a bricklayer to provide for his family following the passing of his father, perhaps it should be no surprise that pressure on the pitch is something he takes in his stride.
"Our scouts deserve a lot of praise for the type of players they bring in and characters," the manager said. "It is really notable. He is a really unique person who has adapted to life very well. He has had to forge this path. He has worked for his journey and grafted. He has got real determination about his personality. He is improving his skill set constantly and we are learning more and more about him. He is a pretty all-round centre-forward."
Their star striker is the headline act but Brentford are not and have never been a single-player team.
While they had star players – Ivan Toney, Christian Eriksen, Mbeumo and Wissa – under Frank, they were always seen as a team stronger than the sum of their parts.
The fear was that once the Dane left, that may not be the case, and that the sum of Brentford's parts alone might not be enough to avoid relegation.
Consequently, appointing Andrews, with a blank managerial CV, and just a twelve months at the club was seen by those outside the club as a huge risk.
A maiden role is a challenge for anyone, let alone when it comes in the Premier League and having made the jump from specialist coach to the manager's office.
But given that Ipswich Town manager one candidate was the only other option that the hierarchy looked at, they were clearly convinced they had the right man.
To date, as often seems to be the case with the key decision makers at Brentford, it looks as if they were correct.
Andrews won just a single of his first five league games in charge but significant home victories against United, Liverpool and Newcastle have followed.
Wins that, following their excellent recent form, could prove increasingly important in the race for Europe.
"We're in fine fettle and playing really good. We are playing with courage and belief in everything we do with or without the ball," Andrews added. "We are pleased with how we are going but we want to keep striving."
In a league where the European spots and the lower mid-table are currently separated by just a handful of points, they have no other option, because things could rapidly look very otherwise.
But, for now, The Bees are defying the predictions. And the longer that continues, the closer to reality those dreams of the continent will become.
