ABU DHABI, Dec 5 : Lando Norris says winning the Formula One world championship would mean everything to him, but being the frontrunner also means he has most to lose. The Briton goes into Sunday's three-way title decider in Abu Dhabi 12 points clear of Red Bull's Max Verstappen with McLaren teammate Oscar Piastri a further four behind. Norris could have wrapped the title up in Qatar last weekend, had results gone his way, and will do so at Yas Marina if he finishes on the podium. Anything less
