Mikaela Shiffrin's results may have dipped slightly since he recently described her as the "best ski racer I've ever seen," but former Olympic champion Bode Miller believes the American will be back to her best when the Pyeongchang Games kick off on Friday.

Shiffrin reeled off five consecutive World Cup victories to start 2018, but has since managed to only stand on the podium once in her last four outings, something compatriot Miller puts down to fatigue.

"She came in so fast and so strong from the pre-season, and all of her preparation was perfect," Miller told Reuters at his hotel in Pyeongchang, where he will work for NBC and Eurosport as an analyst during the Olympics.
