It's still early in the season, but even so, Chelsea's summer business is starting to look questionable.
For example, Jamie Gittens and Alejandro Garnacho do not look at the level required, and Joao Pedro has one goal in his last seven Premier League games.
Moreover, even though Jorrel Hato is one of the most promising young defenders around, he looked out of his depth in the Champions League on Wednesday night.

Fortunately, there is plenty of time for the players to come good, although there is another member of Enzo Maresca's squad who is starting to look like one of Chelsea's worst ever signings: Danny Drinkwater.
Drinkwater's Chelsea career
Drinkwater first shot to prominence when he played a pivotal role in Leicester City's legendary Premier League triumph in the 15/16 season.
The Englishman actually stayed at the King Power Stadium for the following campaign, but then, in the summer of 2017, made a £35m move to Chelsea.
While he was a title-winning midfielder, it felt like something of an unnecessary move from the Blues at the time, but nobody would have predicted quite how poorly it was going to go.
He would only make 22 appearances, totalling 1151 minutes, in his first season, on top of dealing with his role as a squad player, he had to contend with persistent calf injuries.
Unfortunately, the following season was even worse, as in addition to yet more injuries, it also became clear that Marizio Sarri did not fancy him at all, and so he ended the season with a solitary 30-minute appearance in the Community Shield.

The following campaign saw him join Burnley on loan for the first half of the season and Aston Villa for the second half.
However, injuries limited him to two appearances for the former, while a training ground incident saw him return to West London after just four appearances for the latter.
The writing was on the wall at this point, and after a loan to Turkish side Kasimpasa for half a season in 2020/21, he made one more move to Reading the following year, where he made 34 appearances and then retired.
It would be hard to describe Drinkwater's move to Chelsea as anything other than a disaster, and while there were some reasons why, it mostly came down to his inability to remain fit.

Unfortunately for Maresca, it appears that he may now have someone like that in his squad today.
Chelsea's modern Drinkwater
While several players in Chelsea's team have a less-than-ideal injury record, it'll come as no shock that Roméo Lavia is the star in danger of becoming Maresca's own Drinkwater.

Now, before the pitchforks and torches come out, the Belgian has already shown far more in West London than the former Blues man ever did, but that's not really the point.
Like the former Leicester star, the 21-year-old has been so incredibly unlucky with injuries, and it's now got to the point where some fans are questioning whether he should still be at the club come next season.
That might sound extreme, but considering he cost in excess of £45m in 2023, it's really not.
For example, in his first campaign with the club, the midfielder, whom talent scout Jack Kulig once described as having "enormous potential," played a single game.
Then, despite managing 22 appearances last season, they only amounted to 1,069 minutes of action.
This season, he has made seven appearances, totalling 240 minutes, but is now set to be out for some time after suffering yet another injury against Qarabag FK on Wednesday night.

Unfortunately, availability is the best ability, and as one content creator put it, "there is a world-class player in there when he's fit, but that is the case so rarely."
Ultimately, Lavia is a better player than Drinkwater was, but due to his inability to remain fit, his Chelsea career could follow the same path.
