Mercedes team principal Toto Wolff says Ferrari have set a dangerous precedent by utilising team orders so early in the season. Charles Leclerc was ordered aside to let Sebastian Vettel through at the Chinese Grand Prix, although the decision only served to hamper the Monegasque.
Leclerc jumped his team-mate off the line, but Vettel appeared to hold greater pace and was eventually let through, only to then suffer a number of lock-ups and fail to catch the Mercedes cars streaking clear ahead.
Lewis Hamilton went on to lead the third Mercedes one-two from as many races this year, with Vettel on the podium and Leclerc losing another spot to Max Verstappen as his strategy fell apart.
Mercedes used team orders at the tail-end of 2018 as Hamilton was battling Vettel for the title, while Valtteri Bottas had fallen out of contention, but Wolff says doing so at this stage could cause Ferrari headaches.
