This is a crucial moment which recognizes the rise of a young, black British gaffer.'
"He is a top tactician who knows the game inside out, which is the most important thing.
"But, as the Blues' pioneering black footballer, it would be dishonest to claim this news fails to move me."
These were the words expressed by Paul Canoville, who made his groundbreaking first appearance for Chelsea's senior side as a substitute back in April 1982.
On Tuesday, Chelsea appointed Strasbourg boss Rosenior, 41, to be their new head coach following the exit of manager Enzo Maresca.
Strasbourg are within the Todd Boehly and Clearlake Capital-owned ownership group that also owns Chelsea.
Statistics show only twelve of African or Caribbean heritage head coaches – excluding individuals in temporary caretaker roles – in England's top flight since it began thirty-four years ago.
"One thing that impresses me regarding Rosenior is that he was raised and developed his game locally, he understands this community," continued Canoville.
"Whenever youngsters observe a figure like Rosenior managing the team they support, a person they can identify with, from a similar background, from a family that fights for equality… it is impactful and shows them the path is there.
"Indeed, this represents a huge step for the club, for the capital, for every young person with big dreams.
"But right now? We must support Rosenior, provide him with what he needs, and allow him to do his work."
The iconic Dutchman Ruud Gullit was appointed the Blues' manager back in the nineties and became the Premier League's first black head coach.
A dozen years on, by 2008, Paul Ince was appointed as the pioneering black English boss in the top flight after taking charge at Blackburn Rovers.
West Ham manager Nuno Espirito Santo currently stands as the sole additional present Premier League boss of colour.
The scarcity of managers of colour throughout English football corresponds with an absence of diversity at executive level.
According to the Black Footballers Partnership 2023 study, 43% of Premier League players come from African or Caribbean heritage.
Yet, research from the equality organization found only 3.2 percent of board and senior leadership positions across 17 of 20 Premier League clubs are held by people from ethnically diverse backgrounds.
At senior coaching positions, based on figures from eleven clubs, the figure is 2%.
Across all coaching roles – including senior roles – from the same 11 clubs, the statistic is five percent.
"He has undoubtedly made history by virtue of his appointment as a Chelsea manager, and as an organization, we want to witness more such appointments," stated the chief executive of Kick It Out Samuel Okafor.
"It is acknowledged there is a wealth of talent that exists within ethnic minority communities... aspiring coaches want a chance to demonstrate their capabilities. We need to continue to work hard to break those obstacles down."
Furthermore, the new appointee will become one of only four permanent British managers currently in the Premier League – alongside Sean Dyche, Eddie Howe and Scott Parker – which lags behind Europe's other big five leagues regarding homegrown managers.
Sixteen of the 20 first division managers in Serie A are from Italy, Eleven of the 20 in Spain, Twelve in the Bundesliga are German and 10 of the 18 in France.
Current Chelsea caretaker manager Calum McFarlane commented: "I'm sure all young English coaches from an academy background will be, in some way no matter who you support, supporting Liam.
"It is truly inspirational for young English academy coaches to see an individual land such a role with his background and everyone hopes he will be really well."
Rosenior is now the London club's second-ever black coach after Ruud Gullit.
Leroy Rosenior, Rosenior Sr., had a career with the likes of West London clubs, West Ham as well as Queens Park Rangers, with his managerial career peaked with a five-month spell in charge of then-League One side Brentford in 2006.
In 2019, he was awarded a Member of the Order of the British Empire in the Honours List for services rendered in combating discrimination within the sport and wider society.
After Liam hung up his boots he pursued his father's footsteps. He began writing articles for The Guardian, where in 2017 he addressed the lack of diversity of black coaches. He pointed out that ethnicity does not determine ability arguing that opportunities must be awarded based on qualification.
He further expressed the view he would repeat: that vast under-representation results in a failure to understand of players from different cultural and ethnic heritage.
During an interview for a football podcast, Rosenior highlighted the way his star striker, Emmanuel Emegha, had been described as "difficult" and "emotional", noting that he understood the Netherlands international of Nigerian descent. Emegha is set to join him with a move from France to West London this summer.
In further newspaper articles, Rosenior also admitted he was "embarrassed" to hear a coach utter a discriminatory remark. He vowed support for the Premier League's inclusion campaign and authored a public message to Donald Trump while he was in office, accusing him of "overt" racism.
He has subsequently made his name as a manager – first at Hull City, then Strasbourg – and Wayne Rooney said this week Rosenior was "as good a coach as I've ever worked with" following their collaboration at Derby County.
Rosenior said his farewells at Strasbourg earlier this week before signing a six‑and‑a‑half‑year contract at Chelsea.
The Blues had the Premier League's pioneering black manager with Gullit as well as the first black skipper named Paul Elliott.
Elliott has since held multiple senior positions, among them the Football Association's diversity and inclusion board|
