Fernando Alonso is not feeling well, so he missed the press events of the Mexican Grand Prix and will not drive the Aston Martin in FP1 either.
It is true that this last move was planned and is not due to illness, since in the first free practice session it would have been the test driver Felipe Drugovich who took the place of the Spaniard anyway. Aston Martin did not specify what made Alonso ill, let's hope it is nothing serious. If everything goes well and the two-time world champion feels better, then on Saturday night, European time, he could already be on the track in the free practice session.
We do not worry about the "old man", he is a great fighter and would never miss that party where Ayrton Senna, Michael Schumacher or Lewis Hamilton would engrave his name in that certain stone. Moreover, forever.
