Eric Garcia is quietly developing into a legitimate centre-back option for Manchester City, as he continued his fine start to first-team life against Liverpool this week.
Garcia helped City to an impressive clean sheet in the 4-0 win over the new Premier League champions, in his first start since the 3-0 win over Arsenal last month. In fact, this season, Garcia has three clean sheets in four league starts - and five in nine starts in total.
However, the very presence of Garcia, 19, in the heart of defence alongside Aymeric Laporte, should be concerning to City's hierarchy and Pep Guardiola.
Yes, Fernandinho was suspended, but John Stones and Nicolas Otamendi were fit and overlooked for Garcia - a player with just 15 senior appearances going into the game against the league's most fearsome front three this season. However good Garcia looked, he shouldn't really have been needed.
The need for a new centre-back has been blatantly obvious all season, but the inclusion of Garcia against Liverpool was perhaps the biggest indicator yet that new bodies are required this summer.
When the subject of a new centre-back comes up, one name that won't go away is Kalidou Koulibaly of Napoli.
While Koulibaly would undoubtedly offer an improvement in defence, there are plenty of reasons to be dissuaded from making a move this summer.
For one, Koulibaly has just turned 29, and might only have three years or so before City would have to start looking for a replacement again. With Napoli president Aurelio Di Laurentiis insisting that Koulibaly's asking price won't budge, City would be spending a lot of money on a player who will soon be the wrong side of 30.
"If City or United or PSG with €100m (£90m) showed up, I would think about it [selling Koulibaly] and it is probable that they [the player] would leave, always if their will was to leave," De Laurentiis said in June.
If Koulibaly does cost as much as £90m, it would be a considerable sum for a centre-back without Premier League experience and with just 25 Champions League appearances to his name. It would be City's most risky transfer in some time.
However, City are not in a position to be picky this summer. If they were able to drive the price down - which may be possible as clubs deal with fallen incomes due to the global pandemic - then Koulibaly might be the instant improvement they need in defence.
The alternatives, like Pau Torres, Ruben Dias or Nathan Ake, would all come with their own risks, and none have the experience of Koulibaly.
He may not be a long-term solution like Laporte was when he signed in 2018, and there would always be a question mark over his age, and what would be a high transfer fee for a 29-year-old.
But Koulibaly would offer the leadership and strength at the back that City have lacked since Vincent Kompany left. However promising Garcia is, City cannot afford to face Liverpool next season reliant on a teenager as two senior centre-backs sit on the bench.
City are a club who always have the long-term in mind when it comes to transfers. This summer, they have to put the short term first and find the best solution to their most pressing problem. Even if that solution is 29 years old.
