The 19-year-old striker has signed a deal with Bosnia and Herzegovinian club FK Velež Mostar.
Lea’i was at the club on a trial for the last month, and impressed in a match against Croatian side NK Neretvanac Opuzen that convinced Velež to offer him a deal for the next two seasons.
The club’s website describes Lea’i as “the first player in history from the Solomon Islands to sign a professional contract with a European club, and it is clear that a lot is expected of him in that country in the future, and surely the expectations are high in his new club as well.”
