Is there a great wall of worry ahead for Hamilton?

The Chinese New Year was initiated on Friday, so here's Lewis Hamilton taking a shot of the country's amazing Great Wall which is generally recognized as one of the most impressive architectural achievements in history.

The four-time world champion heads into his twelfth season of F1, but with Valtteri Bottas claiming he wants to beat his Mercedes team mate, Sebastian Vettel ready to take on his arch-rival once again and Red Bull's Daniel Ricciardo and Max Verstappen expected to mount a serious charge, is there a wall of worries ahead for Hamilton?

Time will tell...
