The forward joined the London club from Club Brugge for a £30 million fee in the summer of 2024.
Over the midpoint of the campaign, The Bees find themselves in a dream scenario.
With four wins in their last five outings, and a Samba striker banging in the goals, suddenly supporters are envisioning thoughts of trips to Milan, Munich and Barcelona 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 sufficient to secure Champions League football last term.
Solely table-toppers the Gunners have collected 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 predicting this last off-season.
Thomas Frank had left for Spurs after a seven-year stint in charge, a period in which he had not only got the club promoted but also cemented them in the top flight.
Club captain Christian Norgaard left for the North London club and attacking duo Bryan Mbeumo and Yoane Wissa – who scored a combined of thirty-nine goals in the previous campaign – were also sold, joining Manchester United and Newcastle respectively.
Specialist coach Keith Andrews was elevated to succeed Frank, while there was no striker among the summer signings.
A season of difficulty, possibly even the drop, was forecast. But here we are in January with Brentford in the upper echelons.
So, what is behind their success?
Brentford's decision not to bring in another striker was in part down to timing, with Wissa's move not being finalized until the final day of the window.
But they also were aware they had a £30 million striker already chomping at the bit.
The 24-year-old joined from Belgium in July 2024 for a then-record fee, but was hindered by fitness issues in his first campaign, going without a goal in his initial outings.
The 24-year-old 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 most by a Brazilian in a single Premier League campaign.
Considering the countrymen who have come before him, that is some accomplishment, especially with 17 games left to play.
"He's been a breath of fresh air," pundit Danny Murphy said. "He's physically intimidating, quick, powerful, but technically better than people think. Excellent with his feet, either foot, he can score off both. You can see he's full of confidence. His statistics are incredible. He must be so proud. That's a big compliment to him."
That only Erling Haaland, Harry Kane and Kylian Mbappe have scored more in any of the continent's major leagues to this point underscores the standard 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 importance of the initial strike in a game, having someone you can depend on to take that early opportunity cannot be overstated.
Prior to the game against Sunderland, no player to have attempted at least thirty efforts this season has a better shot accuracy rate than Igor Thiago's 59.1 percent.
He finds the target. Do that often enough and the goals will – and have – come.
Considering the hardships he had in his youth, where he labored in construction to provide for 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 credit for the type of players they bring in and characters," Andrews said. "This is really notable. He is a really unique person who has adapted to life very well. 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 developing his abilities constantly and we are learning more and more about him. He is a largely complete centre-forward."
Igor Thiago is the headline act but the team are not and have never been a one-man band.
While they had key individuals – Ivan Toney, Christian Eriksen, Mbeumo and Wissa – under Frank, they were always seen as a team more effective than the sum of their parts.
The fear 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 avoid relegation.
Consequently, appointing Andrews, with no previous managerial experience, and just a year at the club was seen by those outside the club as a huge risk.
A first managerial job is a test for anyone, especially when it comes in the world's toughest league and having made the leap from set-piece coach to the manager's office.
But given that Ipswich boss one candidate was the only other alternative that the hierarchy looked at, they were clearly convinced they had the right man.
So far, as often seems to be the case with the key decision makers at the club, it looks as if they were correct.
The new boss won just one of his first five league games in charge but significant home victories against United, Liverpool and Newcastle have since occurred.
Wins that, following their brilliant recent form, could prove increasingly important in the race for Europe.
"We are in good form and playing really well. We are playing with bravery and conviction in everything we do with and without the ball," he added. "We are happy with how we are going but we want to keep improving."
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 defying the predictions. And the longer that lasts, the closer to fruition those aspirations of the continent will become.
