It's not the first time this season that the McLaren driver has visited Twitter to express feelings and interests. It surprises us that he has time for all that in his busy calendar.
After his Monaco Grand Prix retirement, he was tweeting about his excitement whilst watching the Indy500. And at the same race, Martin Brundle believed his days and races in F1 were numbered after seeing his attitude in an interview.
Despite all this, the Le Mans winner does still seem to care about McLaren and his performances in F1 more than ever before. In Austria, he was standing by the side of his car as engineers worked hard to fix it in practice.
But looking directly at Twitter, nobody would blame you if you said for certain, Alonso is moving to Indycar in 2019.
