New manager Graham Potter got his Chelsea tenure off to a nervy start as Raheem Sterling's opener was cancelled out by Noah Okafor to hold the Blues to a 1-1 draw against RB Salzburg at Stamford Bridge
The result will do little to ease pressure on Chelsea's Champions League Group E campaign, as they remain rooted to the foot of the four-team standings after two games played with a severely dented chance of progressing to the competition's knockout phases
New boss Potter said after the game he was "frustrated" with the result, and though he was proud of his side's application, the former Brighton manager is well aware that the expectation at Chelsea is to win
Chelsea opened their European crusade with a disappointing 1-0 loss to Dinamo Zagreb last week, prompting the sacking of Thomas Tuchel, as he paid the ultimate price for failing to share the new ownership's long-term vision for Chelsea's future
Potter, enjoying his first taste of top-level European club competition, admitted to having never before attended a Champions League match during his official unveiling on Tuesday, let alone occupied top seat in the dugout during one
Sterling claimed the first goal of the Potter era to put Chelsea ahead in the 48th minute, collecting Mason Mount's low cross from the right which was erroneously defended by Salzburg's otherwise impressive rearguard
The unmarked forward was afforded ample time and space to measure a shot, before cooly bending an effort into the bottom right corner from just inside the 18-yard box - a move that will be equally admired by England boss Gareth Southgate, with Reece James also involved
But Salzburg equalised with 15 minutes remaining through top scorer Okafor after Thiago Silva was guilty of diving in to a tackle, allowing substitute Junior Adamu to deliver a dangerous low cross
 Okafor then applied a first-time finish with the aid of a slight deflection off Cesar Azpilicueta's outstretched leg
Chelsea were back in action after the Premier League's weekend hiatus due to The Queen's death, but could not make amends for last week's damaging loss in the Croatian capital
Ahead of kick-off in west London, two Chelsea pensioners laid wreaths on the pitch, while Potter emerged from the tunnel wearing a respectful black suit and tie and thanked home supporters for the warm welcome, before the ground fell silent in memory of The Queen
The Blues, improved in their approach, can still rectify their situation to reach the round of 32, but will likely need to beat AC Milan home and away in their back-to-back matches with the Italians in October
James and Sterling were both sporadically effective in wide positions, but problems remained down the spine of the team, revealing many of the same concerns that dogged performances under Tuchel this term
In forward areas, Chelsea lacked the fluidity needed to create service for the lonely figure of Pierre-Emerick Aubameyang, who again did little to affect the course of the game on his home debut
Chelsea have failed to win both of their opening two matches of a Champions League campaign for only a second time, and first since 1999-2000
"Frustrated with just the one point
 I enjoyed how the players went about their work tonight
 I thought we got Raheem into some good 1v1 situations
 Our response was good to conceding
"But we needed a second goal and it didn't come
 We're disappointed with the one point
"They gave everything
 I was very proud of how they acted
 It's not been easy for them either
 A change of coach and all that comes with that
 They've acted professionally, honestly and taken responsibility
 Effort was 100 per cent there
"I thought we got Raheem into some good situations and scored a good goal
 We can improve as well
 But how the boys approached the game, I'm really happy
"Whatever you do there is always a plus and minus
 We're at home, we wanted to be on front foot
 It's not the position we want to be in - it's a tough group - but there's enough quality in the team and in the squad that we can respond
"We understand the demands of this football club
 I believe in environment and culture
 But I understand we have to win as well
 We're at the start of a process as a group of staff and players
 I want to make this team competitive and a team supporters are proud of
"It's clear to see Potter has inherited a squad of disjointed, disenfranchised players
From Thiago Silva's rash challenging to the isolated, almost non-existent, figures of both Havertz and Aubameyang, there is significant work to be done
Potter cannot simply wave a magic wand
 If fans were expecting to understand what kind of team Chelsea will be under Thomas Tuchel's successor - their performance against Salzburg did little to provide sufficient answers
Many people questioned, scrutinised even, Chelsea's transfer policy over the summer - one that shunned the pursuit of a recognised No 9 yet aggressively chased the deadline day signing of 33-year-old Aubameyang
Perhaps that was a senseless swoop? Time will tell
Chelsea did hold Salzburg in their own half for long periods but at no point did you believe the former Barcelona striker was going to make a discernible difference
 His entries were lethargic, summed up by a wonderful James delivery in the first half which evaded any hint of a target, with Aubameyang casually sauntering past the 18-yard line as the ball fizzed dangerously across the face of goal
It exposed one of Chelsea's numerous shortcomings
 Sterling did indeed take his Champions League goal tally to 25 - the second-most of any English player - but if Potter relies solely on occasional goals from wide forwards, he's sure to come continually unstuck
Chelsea crave a focal point and Aubameyang will be afforded precious little time to impress should his form fail to inspire
 There are ready-made replacements in waiting - expect them to be utilised if he cannot reach the mark
