ABU DHABI, Dec 8 (Reuters) - Lando Norris recognised life would change as Formula One world champion, although he hoped to stay the same as a person, and an immediate sign was the decision made on Monday to race with the number one on his McLaren next season.

The 26-year-old told Reuters Television, a day after he clinched the title in the season-ending Abu Dhabi Grand Prix in a three-way battle at Yas Marina, that he was setting aside his familiar number four.
