The son of Formula One legend Michael Schumacher finished both the Italian and German Formula Four championships in second place this year, and will race in Formula Three in 2017.
Schumacher was spotted at the German Grand Prix earlier this year as a guest of both Mercedes, and another of his father's former teams Ferrari.
At an end of year celebration event near Stuttgart, Schumacher Jr. was pictured by the Express wearing a Mercedes F1 team jacket, with the tabloid adding that his signing "will soon be official, but no one wants to confirm it yet."
