#3 All eyes on high-flying Hazard
On the field, Chelsea's Eden Hazard would be the cynosure of the home support. The Belgian's barnstorming start to the new campaign has been the driving factor behind his side's near-perfect run in the league so far. With seven goals in 8 appearances, he currently leads the scoring pack and would definitely pose a huge threat to the erratic United defence.
He's a menace down that left wing and holds the key to unlocking opposition defenses. Hazard hasn't had much success against the Red Devils so far, netting only five times in 13 appearances, but his rich vein of form holds him in a good stead. The 27-year-old has also come up trumps in set-pieces, netting all three of the penalties he's taken so far.
Chelsea have been functioning as a cohesive unit under Sarri, but Hazard has been that vital cog which has kept the wheels turning. Whether United go with a back five or four, he's going to be the single biggest threat and can even prove to be the difference-maker if he isn't effectively squelched.
