Brighton and Hove Albion have signed midfielder Alexis Mac Allister from Argentinos Juniors.
Albion said: “The 20-year-old has signed a four-and-a-half-year deal and will be loaned back to the Argentinian club for the remainder of the season.”
Manager Chris Hughton said: “Alexis is an exciting young player that we have brought in for the future and he has already made a big impact playing in Argentina.
“It is in the best interests of all three parties to allow him to return to Juniors, as he will be able to continue playing regular first-team football in a very competitive league.
“We will keep a close eye on his development over the coming months, and it is a pleasure to welcome him to the football club.”
Albion added: “Mac Allister came through the Juniors academy and made his senior debut in a goalless draw with Central Cordoba in October 2016 as the club secured promotion to the Argentinian top flight as champions later that season.
“In total, the midfielder has scored eight goals in 58 appearances for Juniors, including three in nine games so far this season.”
