Here’s a relatively uncontroversial statement: Chelsea will win the Premier League title this season. Even after Tuesday’s 1-1 draw with fellow title contenders Liverpool, the Blues hold a nine-point lead at the top of the table with 15 matches remaining and have been the league’s most consistent and terrifying side.

Here’s a slightly more controversial statement: Leicester City, the defending champions who overcame 5000-to-1 odds to claim a fairytale title, will struggle to avoid relegation this season. The Foxes sit in 16th place, 2 spots and 2 points ahead of the relegation zone, tied on points with Swansea City. It seems ever more likely that Claudio Ranieri’s men will scrap it out for the rest of the season to avoid being the first team in England to be relegated in the season following a title since 1938.

Leicester’s troubles this season are numerous and well-trodden. Striker Jamie Vardy, last year’s snarling, trash-talking player of the season with 24 goals, has banged in just five so far this season. Riyad Mahrez, their maestro on the wing, has likewise been ineffectual after a monster showing in Leicester’s title campaign. Despite these difficulties, probably the largest factor in the squad’s drop-off this season—and Chelsea’s dominance—has been the loss of French midfielder N’Golo Kante, who was traded to Chelsea for £32 million this offseason.

Kante’s impact to Leicester’s championship side is hard to understate. As a hard-tackling, Energizer Bunny of a pivot in central midfield last season, he was relied upon for his aggression and shielded the Foxes’ backline while breaking up the flow of opposing attacks. Despite not quite winning the plaudits of Mahrez or Vardy last season, Kante led the league with 156 interceptions and 175 tackles. It was his constant energy and presence in the center of the park—Ranieri said he “must have a pack full of batteries hidden” away—that allowed their attackers to flourish.

The two clubs’ fortunes this season are inextricably linked to gaining and losing Kante. While Leicester has a Kante-sized hole in its midfield this season, Kante has been nothing short of a black hole in Chelsea’s midfield, gobbling up opposing attacks under new manager Antonio Conte, albeit playing a somewhat different role. He’s still breaking up attacks at a dizzying rate, leading the league in interceptions through mid-January, but has shifted his role from the destroyer who helped spring quick Leicester counters to more of a controlling player in Conte’s dominating 3-4-3 formation.

Since its 3-0 drubbing at the hands of Arsenal in late September, Chelsea has been lined up in the same 3-4-3 formation that Conte used while manager of both Juventus and the Italian National Team. The switch to this formation—which sets Kante playing alongside Nemanja Matic in central midfield—has reaped massive rewards. In the Chelsea midfield, Kante’s energy and motor allow him to shield the back three, while also controlling and balancing the pace of the game from the middle of the park by distributing to the wingbacks and attackers. As a result, he’s making fewer defensive stops—which consist of interceptions, blocks and clearances—per game this season. Instead, he has been a more effective passer with nearly 90 percent pass accuracy.

In Tuesday night’s draw against Liverpool, Kante made an astounding 14 tackles, and yet it seemed like a performance where the stats didn’t tell the full story. As Leicester observers last season so often noted of Kante, he covers the ground of two players, something on full display Tuesday. He was first to seemingly every loose ball in the midfield and was critical in disrupting Liverpool’s offensive rhythm, even as the Reds dominated possession and pressed Chelsea.

 Barring a miracle, it’s hard to see any side catching the Blues at the top of the table, especially if the team avenges its early season loss and dispatches of a hot-and-cold Arsenal side in a massive match on Saturday. As it stands, N’Golo Kante is on his way to repeating as Premier League champion and may well be the most valuable—if underappreciated—player in the league.
