Brighton have signed PSG fullback Romaric Yapi.
The Frenchman, 19, has signed a one-year deal with a one-year extension option and will join Simon Rusk's under-23 squad.
"He is another player the club has been aware of for a period of time," said Rusk. "He is a versatile player and is comfortable at right-back, on the right wing or as a wing back.
"He is a talented player who has great potential, and I look forward to working with him."
