Brighton are set to sign Rosario Central midfielder Facundo Buonannote.
The Seagulls have reached terms with Rosario for the 17 year-old prospect.
Brighton will pay around £8-10m to sign Buonannote, plus a 20 per cent cut of any future sell on fee.
He will sign a deal to 2027.
Rosario chief Carlo Tevez said of the teen: "The brake and when he accelerates reminds me a lot of (Lionel) Messi.
"It's been a long time since I've seen a boy play like that, that gives me so much pleasure, and I watch a lot of football. He is at a very high level, one thinks that he has no ceiling, it is where he wants to go. Today he is physically impeccable."
