Both Khabib and Oliveira are known for their ground game. Both are extremely relentless, and rely on their ground control to topple their opponents. In a fame of inches, it won't be wrong to say that Oliveira had the best chance of beating Khabib Nurmagomedov.
Be that as it may, there is no denying Nurmagomedov's dominance on the ground, and his ability to neutralize his opponents. Oliveira is a tough match-up, it's hard to predict, but recency bias suggests, Nurmagomedov gets the job done.
