Igor Thiago signed for the London club from Club Brugge for a club-record fee in the summer of 2024.
Over the midpoint of the season, The Bees find themselves in dreamland.
Following four wins in five games, and a Brazilian striker netting the goals, suddenly Bees fans are dreaming of thoughts of trips to European capitals next season.
A emphatic three-nil win over Sunderland moved their manager's side into the fifth spot in the top flight – a position that was good enough to secure Champions League football last term.
Only leaders the Gunners have accumulated more points over the past six games.
There's a significant distance to go yet but the West London outfit are squarely in the fight for European football.
No one was predicting this last off-season.
The former head coach had departed for Spurs after seven years in charge, a period in which he had not only got the club to the Premier League but also established them in the top flight.
Skipper Christian Norgaard left for the North London club and goal-scoring duo Bryan Mbeumo and Yoane Wissa – who scored a total of thirty-nine goals in the previous campaign – were also sold, joining United and Newcastle United respectively.
Set-piece coach Andrews was elevated to replace the Dane, while there was a notable absence of a centre-forward among the summer signings.
A season of struggle, possibly even the drop, was widely predicted. Yet here we are in January with Brentford in the top five.
So, how have they managed it?
The club's decision not to bring in another striker was in part down to timing, with one forward's move not being finalized until the final day of the window.
But they also knew they had a £30m striker already chomping at the bit.
Igor Thiago joined from Club Brugge 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.
Thiago has set 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.
Given the fellow Brazilians who have come before him, that is a remarkable feat, especially with 17 games left to play.
"He's been a revelation," former Liverpool midfielder Danny Murphy said. "He's physically intimidating, fast, strong, but more skilled than people think. Good with his feet, either foot, 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 Erling Haaland, Harry Kane and Kylian Mbappe have scored more in any of Europe's top five leagues to this point shows the level he is playing at.
And it is not just the volume but the timing of the goals that have been so vital for Brentford.
His opener against the opposition was his seventh first goal of a game of the season. Given 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.
Before the game against their opponents, no player to have attempted at least 30 shots this season has a better shooting accuracy 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 high-stakes situations on the pitch is something he handles with ease.
"The recruitment team deserve a lot of praise for the kind of players they bring in and characters," the manager said. "This is really notable. He is a really unique person who has adapted to life very nicely. He has had to earn this path. He has worked for his journey and grafted. He has got serious grit about his personality. He is improving his skill set constantly and we are discovering more and more about him. He is a largely complete centre-forward."
Their star striker is the headline act but Brentford are not and have never been a one-man band.
While they had key individuals – a host of talent – under Frank, they were always seen as a team more effective than the individual components.
The concern was that once the manager left, that may not be the case, and that the collective quality of Brentford's parts alone might not be enough to stay up.
Consequently, appointing Andrews, with no previous managerial experience, and just a year at the club was seen by those external observers as a huge risk.
A first managerial job 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 Kieran McKenna was the only other option that Brentford looked at, they were clearly confident they had the correct candidate.
So far, as often seems to be the case with the key decision makers at Brentford, it looks as if they were vindicated.
The new boss won just a single of his first five league games in charge but significant home victories against Manchester United, the Reds and the Magpies have followed.
Wins that, following their excellent recent form, could prove all the more important in the race for Europe.
"We're in good form and playing really well. We are playing with bravery and belief in everything we do with and without the ball," Andrews added. "We are pleased with how we are going but we want to keep striving."
In a league where fourth and 15th are currently separated by just eight points, they have no other option, because things could rapidly look very different.
But, for now, Brentford are beating the odds. And the longer that lasts, the closer to reality those aspirations of Europe will become.
