The 21-year-old, who made 11 appearances for the first team last season, will now remain with the club until 2022, with his previous deal having expired at the end of the season.
He will be reunited with new head coach Timo Schultz, who was in charge of the under-17s when Coordes played for them after joining the club from MTV Treubund Lüneburg in 2016.
“Luis has gained some initial experience in the first team and demonstrated that he has the quality to establish himself in the 2. Bundesliga,” said sporting director Andreas Bornemann on the club’s website.
Both Bornemann and Schultz though expect Coordes to kick on in the coming two seasons. “His biggest strength is his pace and the task now is to equip him with the tools to use it effectively,” said Schultz. “My expectation is for him is to exploit his ability in attacking one-on-one situations to the full and pose a much greater threat on goal.”
Coordes himself says he is “delighted” to have agreed a new contract with the club. “I’m convinced that it’s the right path for me,” he added. “I know what the coach expects of me and I’ll work hard to advance as well as possible.”
Schultz’s words will clearly encourage the winger, and he could well be the coach to get the best out of his talent next season.
Although St. Pauli have yet to make any new signings, Coordes is the third to commit his future to the club, with Christian Viet and Marvin Senger signing their first professional deals after breaking through last season.
