The win is ultimately all that matters, but that was a painful watch for Chelsea fans.
Enzo Maresca's side travelled to the Welsh Capital to take on Cardiff City in the quarter-finals of the League Cup on Tuesday night, but didn't look two divisions better off than the hosts.
The Blues looked way off the pace from the first minute, and aside from Alejandro Garnacho and Pedro Neto, it's hard to think of any other players who could leave the pitch with their heads held high.
In fact, it's easier to list those who stood out for all the wrong reasons, including one starter who took fewer touches than Filip Jørgensen and simply has to be dropped.
Chelsea's poor performers against Cardiff
Starting in the back line, and while it sounds harsh, not one of the starting back four had a good game, albeit Josh Acheampong was the best of a bad bunch.
The others all looked rushed in possession, failed to read the game and lost the ball 25 times between them, which would be bad enough against a top side, let alone one in League One.
In particular, there was another concerning display from the most senior defender of the lot, Tosin Adarabioyo.

The 28-year-old looked the most shaky on the ball, completing just 86% of his overall passes and losing the ball the most out of anyone - 13 times.
Moving into the middle of the park, and while Moises Caicedo was one of the West Londoners' better players, he is now going to miss the first leg of the semi-final due to the yellow card he received for petulantly clapping the referee.

If the Blues get drawn against one of the top sides, that could be a seriously costly error.
Finally, up top, it just wasn't Marc Guiu's night.
The young Spaniard wasn't able to cope with the Welsh side's physical nature and ended up missing the one he had in the first half.

The former Barcelona gem was replaced at the break, having taken just a single shot on target, failed to play a key pass, and lost 66% of his aerial duels.
However, there was a starter who was even worse than the striker, someone who simply has to be dropped for the next game.
The Chelsea flop Maresca must drop
For those Chelsea fans who had the misfortune of watching the game, it will come as no surprise that the player who must be dropped is Jamie Gittens.

It's no secret that the Englishman has had a tough start to his Blues career following his mega-money move from Borussia Dortmund in the summer.
In the 19 matches before Tuesday night, the 21-year-old had scored just a single goal and provided five assists, so there might've been hope from the management that a game against a third-tier side would offer the perfect chance for him to bolster his statistics.
Unfortunately, it didn't pan out that way, and the winger once again looked way out of his depth.

For example, in his disappointing 66 minutes of action, he failed to take a single shot on target, didn't attempt a cross, completed just 84% of his 25 attempted passes, lost the ball ten times, failed in 100% of his dribbles and lost 80% of his duels.
Moreover, the youngster took only 41 touches, 17 fewer than Jørgensen, which just goes to show how limited his impact was.

With statistics like those, it's hard to disagree with the Express' Tom Parsons, who gave him just a 4/10 match rating, writing that he was 'was dispossessed too easily' and 'lucky to stay on at half-time.'
Ultimately, there is still plenty of time for Gittens to turn things around at Chelsea.
However, if he keeps on putting in performances like the one against Cardiff, then it'll become harder and harder to disagree with one analyst's claim that he's been a "pointless signing.
