Testing verdict: Where exactly is Mercedes at after week one?
Mercedes made good on its promise to finally show some pace on the final day of the opening Formula 1 test of 2019, proving it had been holding back on the first three days.

Former F1 technical director Gary Anderson and Autosport’s Jack Benyon join Glenn Freeman in Barcelona to discuss the good and the possibly bad news for Mercedes, plus what we can read into the teams that set the pace on the final day: Renault and Toro Rosso.
