Alonso has long-stated his wish to keep the door to F1 open, with McLaren confirming last month that the two-time world champion would be testing its 2019 car at some stage this season, as well as playing a role in the development of its 2020 car.

McLaren confirmed on Thursday that Alonso's F1 testing return would come in Bahrain next week, when he completes one-and-a-half days of Pirelli tyre test running on Tuesday and Wednesday.

Alonso will complete a full day behind the wheel of the MCL34 car on Tuesday before splitting duties with Carlos Sainz Jr. on Wednesday, heading out for the afternoon session.

Full-time drivers Sainz and Lando Norris will share regular test running in Bahrain, doing half a day each on Tuesday before Norris does the full complement of running on Wednesday.
