Day of truth for Lawson? Will he force F1 seat at RB20 test?

Liam Lawson will be in action at Silverstone today during a filming day with the RB20. According to Red Bull Racing itself, the test had been planned for some time, but one can hardly be separated from the other. Sergio Perez has been underperforming for some time and the pressure on him is only increasing. Can Lawson convince Red Bull's management on Wednesday that he should take over an F1 seat in the second half of the season?
