After Antonio Rudiger's freak own goal levelled the score at 1-1 for a hopeful Sheffield United as he rolled the ball into his own net, it looked doubtful that Chelsea would be taking home the three points.
Jorginho converted the spot kick in his signature "hop skip jump" fashion to make it 2-1. Chelsea saw the rest of the game out with some solid defending.
Thomas Tuchel's substitutions injected the winning team with fresh legs and fresh ideas, outplaying the hosts all about the park.
Timo Werner finally finding his feet?
Suprisingly, Werner was outstanding on the evening, earning himself the man of the match award. Although the striker didn't score he assisted for the first goal and won a penalty, proving instrumental to Chelsea's win.
Positioned just behind and wide of target-man Olivier Giroud, Timo made darting and intuitive runs in behind the back line, creating space for the likes of Mount and Mateo Kovacic to run into. This is how the Blues managed to carve out the majority of their key chances.
Perhaps the marksman is starting to find his form due to Tuchel bringing in his right hand man of late to Stamford Bridge - Zsolt Low. Zsolt was part of the backroom staff at RB Leipzig from 2016 to 2018 and oversaw the development of Timo Werner from young prospect to Bundesliga enigma.
Chelsea seem to have more in the tank
A common denominator under last Blues boss Frank Lampard was that the West-London side always seemed to either lose grip of a lead, or throw one away before the 90 minutes were up.
Although only four games in as new boss, Tuchel seems to be getting the most out of his players and seeing out winnable games. Chelsea have struggled with consistent performances over the last couple of years and usually failed to impress when playing against lower ranked teams in the league.
Sheffield United actually beat them 3-0 last time the two sides met at Bramall lane, topping off a season that the Blades have been unable to replicate this year.
Rather than there being discomfort in the squad as to who is starting games and in the managers good books, it seems that the Chelsea squad is more of a cohesive unit under their new manager. With substitutes coming off the bench to help get their team over the line, instead of trying to impress individually, there is a positive aura growing around Stamford Bridge.
