Jan 4 (Reuters) - Johannes Hoesflot ‌Klaebo and Jessie Diggins clinched the overall Tour de ‌Ski cross-country titles on Sunday, sending a clear warning shot ‌ahead of the Olympic Games.

Norwegian Klaebo, now a fifth overall Tour de Ski title winner, further underlined his status as the man to beat as he ‍targets another clean sweep at the Milano ‍Cortina Winter Games next month ‌after winning six golds in six events at last year’s World ‍Championships.
