Rosenior’s tenure at Strasbourg will go down as a resounding success. Tasked with developing young talent - often players on loan from Chelsea - while maintaining competitiveness in a difficult league, he exceeded expectations. He leaves France having guided Strasbourg to a formidable position in Ligue 1, playing a brand of progressive football that evidently caught the eye of the ownership group led by Todd Boehly and Behdad Eghbali.
Reflecting on his time across the Channel, Rosenior was effusive in his praise for the French club, insisting that his success was a collective effort rather than a solo endeavour.
"It's been the best 18 months of my professional career here at Strasbourg," he stated. "I have met some incredible people and none of that happens without the hard work of everyone connected with this football club."
Crucially, Rosenior was keen to point out that his move to Chelsea was not a foregone conclusion simply because of the shared ownership. His performances in Ligue 1 had attracted attention from across Europe’s elite, validating his credentials as a top-tier manager in his own right.
"It's not just Chelsea, I have had interest from other Champion League clubs," he revealed, silencing critics who might suggest this is purely an internal promotion. "But this opportunity, I can't turn down."
