'It's a key moment which recognizes the rise of a young, black English head coach.'
"He is an excellent coach who understands the game back to front, which is the crucial factor.
"However, as Chelsea's pioneering African heritage footballer, I would be lying if I said this moment does not affect me."
Those are the words of Paul Canoville, who earned his historic debut for Chelsea's senior side off the bench back in April 1982.
This week, Chelsea named RC Strasbourg boss Rosenior, 41, to be their next head coach following the departure of Enzo Maresca.
The French club is part of the Todd Boehly and Clearlake Capital-owned ownership group which also controls Chelsea.
Statistics show a mere twelve black head coaches – not including those in temporary caretaker positions – in the Premier League since it began thirty-four years ago.
"What really strikes me about Liam is that he grew up and developed his game not far from here, he understands the local fans," continued Canoville.
"Whenever children observe someone like Liam in charge of their club, a person they can identify with, who's from their ends, who comes from a household that champions equality… that's powerful demonstrating the path is there.
"Indeed, this represents a huge moment for the club, for the capital, for every young person with big dreams.
"But right now? We must support Rosenior, give him what he needs, and let the man do his work."
The iconic Dutchman Ruud Gullit became the Blues' head coach in 1996 and became the Premier League's inaugural African heritage manager.
A dozen years on, in 2008, Paul Ince became the first black English boss in the Premier League after taking charge at Blackburn Rovers.
West Ham boss Nuno Espirito Santo currently stands as the only other current Premier League boss of colour.
The lack of managers of colour across English football corresponds with a lack of diversity at executive level.
As per a BFP 2023's report, forty-three percent of Premier League footballers are from African or Caribbean backgrounds.
However, analysis from the equality organization found only 3.2 percent of board and senior leadership positions at 17 of 20 Premier League clubs are from minority ethnic backgrounds.
Regarding senior coaching positions, based on figures from eleven clubs, the figure is 2%.
Across all coaching positions – including head coaches – from the same eleven clubs, the figure is just 5%.
"He has undoubtedly broken barriers in terms of his appointment as Chelsea manager, and we hope to witness more such appointments," said Kick It Out CEO Samuel Okafor.
"We know there is loads of ability present in the black and underrepresented communities... aspiring coaches want the opportunity to show what they can do. It is imperative to continue to work hard to break those obstacles once and for all."
Furthermore, the new appointee will become one of only four permanent British head coaches currently in the Premier League – alongside Sean Dyche, Eddie Howe as well as Scott Parker – which trails the continent's other big five divisions in terms of national representation.
Sixteen of the 20 top-flight coaches in Italy are Italian, Eleven in La Liga are Spanish, 12 in the Bundesliga in Germany while 10 in Ligue 1 are French.
The present Blues caretaker manager Calum McFarlane commented: "I'm sure all young English managers from an academy background are, in some way regardless of allegiance, supporting Liam.
"It is really inspirational to up-and-coming British academy coaches to see an individual get that job with that profile and we hope he will be really well."
Liam Rosenior becomes Chelsea's second black manager after Ruud Gullit.
His father, Leroy, Liam's father, had a career with the likes of West London clubs, the Hammers as well as Queens Park Rangers, with his coaching stint culminating in a five-month stint in charge of then-League One side Brentford back in 2006.
In 2019, he received a Member of the Order of the British Empire in that year's Honours List for services rendered to tackling discrimination in football and beyond.
After Liam hung up his boots he pursued a path in management. He started writing articles for a national newspaper, and in one piece he acknowledged the lack of diversity of black coaches. He pointed out that ethnicity does not determine coaching skill and said roles must be awarded based on qualification.
He further expressed a point he would repeat: that vast lack of diversity results in a failure to understand regarding footballers from different ethnic and cultural backgrounds.
During an interview with The Athletic FC, Rosenior highlighted how his leading forward, Emmanuel Emegha, had been described as "hard to manage" or "passionate", noting that he could relate to the Dutch international of Nigerian descent. Emegha is set to follow him in moving from Strasbourg to West London this summer.
In subsequent newspaper articles, Rosenior also admitted to being "embarrassed" upon hearing a coach utter a discriminatory remark. He vowed his support for the Premier League's inclusion campaign and wrote an open letter to the former US President while he was in office, condemning his "overt" racism.
Rosenior has since made his name in the dugout – first at Hull City, later at Strasbourg – with Wayne Rooney recently stating Rosenior was "among the best coaches I've ever worked with" after their collaboration at Derby County.
The manager bid his farewells to his former club on Tuesday morning prior to putting pen to paper on a long-term contract at Chelsea.
The Blues had the Premier League's pioneering black manager in Gullit and the first black skipper in Paul Elliott.
Elliott has since worked in multiple senior positions, including the FA's diversity and inclusion board|
