Lewis Hamilton may have been looking back on last winter's choice to join Ferrari after Friday's testing in Bahrain ended, with former Mercedes team-mate George Russell topping the time sheets.
Teams spent 24 hours each on the track from Wednesday-Friday this week, with Hamilton beating out new Ferrari team-mate Charles Leclerc, although times aren't expected to be representative of teams' true pace.
In Friday's running, Hamilton finished sixth fastest, with Russell, Max Verstappen and Alex Albon making up the top three.
However, it is Albon's Williams team-mate Carlos Sainz who can be crowned the champion of testing, setting the fastest time of the three days with a time of 1:29.348 seconds set on Thursday.
This chaotic driver swap resulted in a hit in testing time for both Stroll and for the Silverstone outfit, who were faced with the task of having to switch driver setups mid-session, a time-consuming effort.
