The move, confirmed by the Blues on Monday, sees the Belgian talent join the French side as part of their shared BlueCo ownership model, designed to nurture young stars.
Penders, who arrived at Chelsea from Genk in January 2025 for around 20 million euros, spent the second half of last season with his boyhood club, making 26 appearances and earning praise as one of Belgium's brightest prospects.
Standing at an imposing 2.00 meters, he has already captained Genk's reserve side and represented Belgium at youth international level.
"This loan is a fantastic opportunity for Mike to test himself in a top European league," Chelsea said in a statement on their official website. The Blues expect Penders to compete for the number one spot at Strasbourg, who are preparing for the 2025-26 UEFA Conference League campaign under coach Liam Rosenior.
The departure of last season's standout goalkeeper Djordje Petrovic to Bournemouth for 25 million pounds has opened the door for Penders to stake his claim.
Strasbourg's pre-season camp in Austria will be Penders' first chance to impress, with Chelsea confirming he has already joined his new teammates. "We look forward to monitoring and supporting Mike's development throughout his loan," the club added.
Fellow Chelsea youngster Kendry Paez is also set to link up with Strasbourg soon, strengthening the BlueCo pipeline.
The move marks Chelsea's seventh loan departure this summer as head coach Enzo Maresca reshapes the squad. "Penders is an outstanding elite talent," said journalist Matt Law, reflecting sentiment within the club. "They believe he could become one of the best goalkeepers in the world."
For Penders, the goal is clear: seize this chance to shine in Ligue 1 and return to Stamford Bridge ready to challenge for a first-team spot.
This strategic loan underscores Chelsea's commitment to developing their young stars through competitive first-team football, with Strasbourg providing the perfect stage for Penders to prove his potential.
