LA Galaxy have completed the loan signing of Cristian Pavon from Boca Juniors, the club announced on Thursday.
Pavon, 23, becomes the first signing for the Major League Soccer side in this transfer window.
"Cristian is a young and dynamic attacking addition who has the talent to be one of the most effective offensive players in Major League Soccer," LA Galaxy General Manager Dennis te Kloese said in a statement.
"He is a high-caliber player who will be a valuable piece to our roster moving forward. By providing him with a stable environment and a coach he knows well, we are confident that he can continue to grow and improve as a player within our club. We are extremely excited to add him to our squad and look forward to his contributions with the LA Galaxy."
Sources told ESPN FC that the Galaxy attempted to sign the forward on a permanent deal but were unable to agree on a fee.
Both clubs have now negotiated an agreement which will see the Argentina international join on loan for the remainder of the campaign.
Pavon played every match for Argentina in the 2018 World Cup in Russia and scored four goals in 19 appearances for Boca last season.
