Crusaders winger Stuart Dallas will move to English League One club Brentford in the summer after signing a pre-contract agreement with the Bees.
Dallas, 20, made his Northern Ireland debut in last year's Nations Cup.
He was named the Northern Ireland Football Writers player of the year last season and has helped his club reach this year's Irish Cup final.
Brentford are managed by former East Germany international and ex-Manchester City striker Uwe Rosler.
Another Northern Ireland winger Niall McGinn is currently on loan at Brentford.
