Cesc Fabregas had decided to have a day off in midfield as the Spaniard struggled to have any impact in the first half. No matter, though, because Chelsea had N'Golo Kante.
The former Leicester City workhorse did both of their jobs. He hounded Southampton into submission, showing why he is a leading contender to become the club's Player of the Year.
Kante has always been hailed for his ability to tackle but the 27-year-old can do so much more. At Chelsea, the 5ft 6in midfielder has added to his game, and he was integral in this Wembley win.
