The report says Trossard arrived in camp motivated and eager for the tournament after finishing a strong season with Arsenal. That matters. International football can turn quickly on confidence, and he appears to be carrying plenty of it.
He is not the sort of attacker who needs a game to be built entirely around him. What he offers is flexibility:
For Belgium, that profile can be vital in tournament football, where one opening can decide everything.
There is also a separate storyline hovering over him: what comes next at Arsenal. Reports suggest his longer-term future remains open, but this is where Trossard seems to have drawn a line. Rather than feeding that debate, he has pushed it into the background.
That feels sensible. Players often talk about staying in the present during major tournaments, and in his case it rings true. The report says he spoke with pride about his recent club campaign while keeping the emphasis on representing his country.
For Belgium, the value is obvious. Tournament squads need talent, but they also need players arriving with clarity. Trossard appears to be doing exactly that - backing his form, embracing responsibility and keeping distractions to a minimum.
The next step is simple: turn that confident tone into influence on the pitch. If he starts the World Cup as brightly as he sounds, the conversation around Belgium may quickly become less about transition and more about threat. And once the tournament is over, the questions about Arsenal will still be waiting.
