Brighton winger Jeremy Sarmiento has joined West Brom on a season-long loan.
The 21-year-old Ecuador international's arrangement doesn't include a permanent option.
"I am very pleased to have signed a talented player from a Premier League club," said WBA manager Carlos Corberan. "He is an exciting player, who has great maturity for someone so young.
"The fact he has already played in the Premier League and at a World Cup gives me the confidence that he has the personality and desire required to keep developing his skills.
"He is a versatile attacker who can play on either wing, as well as through the middle as a 10. His flexibility to play to a high standard in three different positions will be important."
