The forward joined Brentford from Belgian side Brugge for a £30 million 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 supporters are dreaming of 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 position that was sufficient to secure Champions League football last term.
Only table-toppers the Gunners have accumulated more points over the past six games.
There is a long way to go yet but the West London outfit are firmly in the battle for European football.
No one was forecasting this last summer.
Thomas Frank had departed for Spurs after a seven-year stint in charge, a period in which he had not only got the club promoted but also established them in the top flight.
Skipper their Danish midfielder left for the North London club and attacking duo Bryan Mbeumo and Yoane Wissa – who scored a combined of 39 goals in the previous campaign – were also sold, joining Manchester United and Newcastle United respectively.
Set-piece coach Keith Andrews was promoted to succeed the Dane, while there was no striker among the off-season arrivals.
A year of difficulty, possibly even the drop, was forecast. But here we are in January with Brentford in the top five.
So, how have they managed it?
Brentford's decision not to bring in another striker was partly down to timing, with Wissa's move not going through until deadline day.
But they also knew they had a £30 million 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 fitness issues in his debut campaign, going goalless in his initial outings.
Thiago 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 most by a Brazilian in a single English top-flight campaign.
Considering the countrymen who have preceded him, that is some accomplishment, especially with seventeen matches left to play.
"He's been a breath of fresh air," pundit Danny Murphy said. "He is a physical specimen, fast, strong, but more skilled than people think. Excellent with his feet, both feet, he can score with both. You can see he's full of confidence. His statistics are fantastic. 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 Europe's top five leagues to this point underscores the level he is playing at.
And it is not just the quantity but the timing of the goals that have been so important for Brentford.
His first goal against the opposition was his seventh first goal of a game 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 first big chance cannot be overstated.
Prior to the game against Sunderland, 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 finds the target. Achieve that often enough and the goals will – and have – come.
Given the hardships he had earlier in life, where he labored in construction 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 credit for the type of players they bring in and personalities," Andrews said. "It is really impressive. He is a really special 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 developing his abilities constantly and we are learning more and more about him. He is a largely all-round centre-forward."
Igor Thiago is the man of the moment but the team are not and have never been a single-player team.
While they had key individuals – Ivan Toney, Christian Eriksen, Mbeumo and Wissa – under their previous boss, they were always seen as a team more effective than the sum of their parts.
The fear was that once the Dane 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 a blank managerial CV, and just a year at the club was seen by those external observers as a huge risk.
A maiden role is a test for anyone, let alone when it comes in the Premier 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 Brentford looked at, they were clearly convinced they had the correct candidate.
To date, as often seems to be the case with the brains trust at the club, it looks as if they were spot on.
Andrews won just a single of his first five league games in charge but big home victories against United, the Reds and Newcastle have since occurred.
Wins that, following their excellent recent run, could prove increasingly important in the race for European qualification.
"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," Andrews added. "We're happy with how we are going but we want to keep pushing."
In a league where fourth and 15th 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 beating the odds. And the longer that continues, the closer to fruition those dreams of the continent will become.
