Ross Tierney has agreed to join Motherwell.
The Republic of Ireland Under 21 international will arrive on 1 January at the start of the winter transfer window.
Joining from Bohemians, Tierney has signed a three-and-a-half-year deal. The club has paid an undisclosed fee for his services.
“We’re really looking forward to Ross joining the club in January,” Motherwell boss Graham Alexander said.
“He’s a young player who has had a couple of excellent seasons with Bohemians and his national squad.
“His attributes will fit in perfectly with how we play and his potential is unlimited at this stage of his career.
“He’s already met the squad and is excited about the move. We mirror those feelings.”
Tierney, 20, is one of the most exciting talents in the League of Ireland, having already made 67 appearances for Bohs.
The attacking midfielder was recently nominated for PFA Ireland’s Young Player of the Year, capping off a season where his side reached the FAI Cup final.
Bohemians also played their way through to the third qualifying round of the UEFA Europa Conference League, defeating Stjarnan, Dudelange and PAOK before eventually losing to the Greek side on aggregate.
Tierney netted twice on that run, scoring decisive away goals in Iceland and Luxembourg.
His talent also saw him included in Ireland’s Under 21 squad, where he scored a headed winner against Australia on his debut in June, in the first of his five caps to date.
