The 24-year-old is pushing for this season’s Premier League golden boot, with 21 goals from his 34 games, just three off Manchester City’s Erling Haaland.
According to ESPN Brazil, it would take an offer of £80 million to convince Brentford to sell Thiago this summer.
They add that Chelsea and Atletico Madrid have both made enquiries to Brentford regarding the striker.
Juventus and AC Milan are keen too, but Brentford’s asking price makes a move to Italy all but impossible.
