LONDON -- Thomas Tuchel is not one of Chelsea's most expensive signings, but he showed in Sunday's 3-0 Premier League win at Tottenham that he is rapidly becoming one of the club's best.
The leap in stamina required from Champions League winners to Premier League title contenders requires precisely the sort of managerial acumen Tuchel delivered to turn a tight game into a comfortable win.
Of course, it helps when a player with the calibre of N'Golo Kante is at your disposal off the bench as a half-time substitute with the game goalless, but Tuchel sensed an opportunity by taking off Mason Mount and adjusting his 3-4-2-1 system in an intervention from which Spurs never recovered.
