Leo Erik Jean Cornic (born 2 January 2001) is a Norwegian footballer who plays as aàdefender for the Norwegian professional football club Tromsø.
In 2010, nine years old, Cornic started playing for VÃÂ¥lerenga's youth teams. He would later rise through the ranks and found himself playing for their second team in the Norwegian Second Division by 2018. The same year, Cornic signed his first professional contract with the club, lasting until the end of the 2020 season. In 2019 he would get his debut for the first team, in a cup tie against Faaberg, which would go on to be the only game he would play for VÃÂ¥lerenga's first team.
After impressing with his appearances for VÃÂ¥lerenga's second team, Cornic was loaned out to Bærum for the latter half of the 2019 season. Cornic was capped ten times for the Norwegian Second Division side, before returning back to VÃÂ¥lerenga.
Ahead of the 2020 season, Cornic was sold to newly promoted Norwegian First Division club Grorud.
After only one season at Grorud, Cornic moved to Swedish side DjurgÃÂ¥rdens IF on a four-year contract. The sale marked Grorud's first time selling a player to an international club. At DjurgÃÂ¥rden Cornic struggled to establish himself as a starter, and would go on to appear only fifteen times in all competitions over his two seasons there.
On 15 August 2022, after one-and-a-half seasons at DjurgÃÂ¥rden IF, Rosenborg announced that Cornic had signed on for them until the end of 2026. Cornic cited that he chose Rosenborg because they were the biggest club in Norway, and that he believed in the head coach Kjetil Rekdal. In the summer of 2023, Cornic scored the winning goal in the second round of the 2023âÂÂ24 UEFA Europa Conference League qualifying against Crusaders.
After gradually losing his starting position at Rosenborg under their new head coach Alfred Johansson, Tromsø wanted to sign Cornic in the summer of 2024. On 31 July, he was announced as their new signing, on a contract running through the 2027 season. Only four days after signing with Tromsø, Cornic headed back to Lerkendal Stadion to face his former teammates in a 1âÂÂ0 defeat, playing the last twenty minutes of the game. The same month Cornic would go on to play both of Tromsø's third round fixtures against Scottish club Kilmarnock in the 2024âÂÂ25 UEFA Conference League qualifying, eventually losing out 3âÂÂ2 on aggregates.
Cornic's father is French, and he spent some time in his childhood living and playing football in France.
