Brighton have completed the signing of Argentine midfielder Alexis Mac Allister from Argentinos Juniors.
The 20-year-old has signed a four-and-a-half-year deal with the Seagulls but will stay in the Superliga for the rest of the season.
Argentinos confirmed in a statement Brighton have paid $9 million (£6.9m) for their 90 per cent share of Mac Allister's economic rights.

Brighton boss Chris Hughton feels Mac Allister, who has made nine league appearances for Argentinos this term, will be a good addition to his squad for the 2019-20 campaign and beyond.
"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," Hughton told Brighton's website.
