A last-gasp Tammy Abraham goal completed an emphatic second-half comeback as Chelsea came from three goals behind to draw 3-3 against West Brom.
It was the worst start possible for The Blues as they found themself three goals down after just 27 minutes. A brace from Callum Robinson was topped off with a goal from Kyle Bartley in the first half-hour to send The Baggies into the break much better off then they could have imagined.
Chelsea boss Frank Lampard made a double change at half-time which proved the difference for the last 45 minutes, with substitute Callum Hudson-Odoi scoring in-between a Mason Mount and Abraham goal to assure The Blues left with a point.
Academy boys bail out Lampard's side.
After spending over £200 million this transfer window to improve his side and ensure a title-challenging season, it was a trio of academy graduates who scored all three Chelsea goals and earned the South-West London side a point at The Hawthorns.
The introduction of Hudson-Odoi at half-time put the game in Chelsea's favour for the second half. The 19-year-old was the catalyst for Lampard's side and scored a brilliant goal to reduce the deficit to just one goal.
Mount opened Chelsea's account with a stunning long-range effort to kick-start the comeback, and the creative threat offered from Mount was superior to new-boys Kai Havertz and Timo Werner, although the German duo will still need time to adapt to the Premier League.
Even though he didn't have the greatest game and missed a golden opportunity in the first-half, Lampard's patience with Abraham paid-off when the 22-year-old poked home at the death to level the game.
Chelsea's defensive problems aren't an overnight fix
With the introduction of Thiago Silva last night into the heart of Chelsea's defence, many fans were expecting all their recent defensive problems to disappear. This was far from the case.
The experienced Brazillian centre-back was at fault for the second West Brom goal when a lack of concentration from the 36-year-old allowed Robinson through on goal for his second of the night.
It was unexpected seeing such an experienced defender have a hard time against a newly promoted team, however a big part played in this could be from the position he was playing.
For Paris Saint-Germain, Silva played as a right-sided centre-back, and for Chelsea, he's being played on the left. On paper it doesn't seem like such a big change, however when you are playing with a new team and are on a different side of the pitch, it's understandable to why he looked uncomfortable on the ball. The Brazillian's lack of English also makes it hard for him to replicate the leadership role's he's played at past clubs.
With the signings of Silva, Ben Chilwell and new goalkeeper Edouard Mendy, their defence is destined to improve, however they must be given time to adapt to Lampard's system and gel together.
Attack isn't the problem for The Baggies
Slaven Bilic's men have now scored five goals in two games against two very good sides in Everton and Chelsea.
Albion fans always knew that the start to their Premier League campaign would be a tricky one with Leicester City, Everton and Chelsea in their first three, and even though they've only taken one point away from those fixtures, there are plenty of positives to take.
Attacking duo Grady Diangana and Matheus Pereira have been the standout players for The Baggies, with the latter having three-goal involvements in as many games. Robinson scored two against Chelsea which will provide a massive confidence boost for the Ireland international, and with Bilic still in the market for a new striker, it can only get better for the West-Midlands side.
Unfortunately, that's where the positives end for Albion. Their defensive line was shaky once again, and as good as the Chelsea attack is, to surrender a three-goal lead isn't good enough no matter the opposition.
That's now 11 goals conceded in just three league games, and if Bilic can't find a solution for his leaky defence soon, it could mean more problems for West Brom this season.
