Luis Diaz is he first Columbian player to appear for Liverpool FC. Born in 1997, he was raised in Barrancas, not far from Columbia's border with Venezuela. However the first time he left the country was in 2015 when he represented Columbia in the Copa America of Indigenous People, held in Chile. He scored twice as Columbia reached the final, losing to Uruguay. Diaz had now done enough to secure his first professional contract and he signed for second tier Barranquilla, an affiliate club of leading side Atletico Junior. There was no doubt about his talent but there were concerns over his ability to meet the physical demands of the game. A pasta diet, which saw him gain ten kilos, soon resolved that and by 2017 he was ready to take the step up to Junior. He won the league title, reached the Copa Sudamerica final and became a regular for the national side. It was no surprise when European clubs came calling and in 2019 he joined Porto.
Diaz earned international recognition when he was the joint top-scorer with Lionel Messi with four goals in Copa America in 2021 when Colombia finished third. Diaz continued his scoring exploits with Porto in 2021/22 with 14 goals in 18 appearances in the Primeira Liga. His speed, aggressiveness in the final third and a deadly eye for goal fits perfectly with Klopp's style of play and Liverpool were tipped to make a move for him in the summer. However when Spurs looked to have agreed a fee with Porto in the January transfer window, Liverpool stepped in, sending a delegation out to Argentina where he was on international duty to secure the deal and conduct a medical. Despite only arriving on Merseyside 48 hours beforehand, Diaz played half an hour of Liverpool's fourth round FA Cup tie with Cardiff at Anfield, setting up a goal for Takumi Minamino.
