Chelsea
Ngolo Kante
Chelsea won the FA Cup in 2018, but their Premier League retention campaign was far from impressive. Defeating former manager, and club legend, Jose Mourinho in the FA Cup final was one thing. But finishing fifth in the league was another.
League winning manager Antonio Conte left the club in the summer, with Napoli boss Mauricio Sarri taking his place. Sarri and his noted "Sarriball" initially took good effect, until their unbeaten run ended at Tottenham Hotspur.
Moreover, some of Chelsea's players excelled at the World Cup, including Ngolo Kante and Olivier Giroud with France, and Eden Hazard with Belgium which attained third place.
The standout player though, I feel, is Ngolo Kante.
Hazard dipped a little since the title win in 2017, though Kante overall has been the most consistent. He is arguably the best in the world of his position, and his rise to the pinnacle of world football is mesmerising. He was largely unknown a few years ago but then won back to back Premier League titles with Leicester City and Chelsea, and a World Cup with his country.
His presence on the pitch, and his relaxed persona off it, all lend to his class.
