Lewis Hamilton admitted he underperformed throughout the Chinese Grand Prix weekend after having to settle for fourth position.
Many had expected Mercedes return to the front in China but the world champions struggled for pace and were comfortably beaten to pole by Ferrari. Hamilton was out-qualified by teammate Valtteri Bottas and then lost out to Red Bull's Max Verstappen at the start.
Mercedes missed the opportunity to mirror Red Bull's race-winning strategy at the Safety Car period, meaning Hamilton was easily passed by Daniel Ricciardo in the closing stages.
"I was in no man's land today," Hamilton said after the race.
