At full-back, for a squad that cost so much to assemble, Chelsea are hardly spoilt for choice.
Left-back, in particular, has been an area where the Blues have looked extremely vulnerable this season, with Marcos Alonso having struggled to cope with the team's transition from a back three to a back four.
Considering that, with Jay Dasilva now possibly heading for the exit door, the Stamford Bridge hierarchy could end the summer with a lot of questions to answer.
All things considered, the 21-year-old looks an ideal option in this moment of time and could have been a great addition to the squad amid the west London club's transfer ban, providing adequate competition for Emerson.
But with Bristol City manager Lee Johnson hinting Dasilva's loan move could be about to become a permanent (Sound of the City via Bristol Live) one, the Chelsea faithful will probably now never know.
Given Dasilva's ability and potential, it is a surprise the Blues have come to such an arrangement with Bristol.
Technically, the England U21 international is superb. He can take the ball past his opponent and get out of tight spots with the skill he possesses.
For an offensive-minded coach, Dasilva is close to being the dream full-back.
The above does not necessarily mean Dasilva would come in and be an instant fix for the Blues but the foundations are there for him to go on and make a name for himself.
It really would be a disaster if he was to leave as he has all the ingredients to become a star at Stamford Bridge and they're not exactly blessed with the best of options at left-back. And, with the transfer ban hanging over Chelsea's head at this moment in time it would be very stupid of them to let a player like Dasilva leave permanently.
Chelsea have been known to sell players who have gone on to become superstars, with Mohamed Salah and Kevin De Bruyne being fine examples of that. And, Dasilva could be the next if he ends up leaving.
