The Chilean, currently plying his trade with domestic club O'Higgins in the Primera División, is reportedly close to finalising a deal.
Per his agent:
The negotiations are very advanced with Chelsea.
There are still a few details, but the situation is very advanced.
Chelsea have been following him for a couple of years, and the offer was made due to his good performances.
The touted fee is between £2 million and £3.5 million, with the youngster likely staying in South America on loan initially. But what are the Blues getting?
Cuevas is a left midfielder who played as a true winger throughout the recent Sudamericano Sub-20 tournament under Mario Salas.
La Roja weren't prospering in the previous 3-4-1-2 formation, so a switch was made which was largely considered a success.
According to Joel Sked, however, he still wasn't the focal point of attack, with the lion's share of football going through "future midfield king" Bryan Rabello.
Still, from the video, it's clear he's a tricky outlet and a useful presence in the side. He can cross, dribble and beat a man, while he also shows remarkable robustness considering his slight figure and age.
If Chelsea land his signature, when would we likely see him don a Blue shirt and trot out onto the Stamford Bridge turf? 2016?
As long as he gets the chance to prove himself when he's ready or head out on loan, this can only be a good move for Chelsea.
