'It's a key event that celebrates the rise of a young, black British manager.'
"Rosenior represents a top coach that understands football inside out, and that's the most important thing.
"But, in my role as the Blues' first African heritage player, I would be lying to claim this appointment does not affect me."
Those are the words of Paul Canoville, who made his historic first appearance for the Blues' first team off the bench in the spring of 1982.
This week, the club named Strasbourg boss Rosenior, 41, to be their next head coach after the departure of Enzo Maresca.
The French club is part of the multi-club BlueCo that also owns the London club.
There have been just twelve of African or Caribbean heritage managers – not including those holding temporary caretaker roles – in the Premier League since its inception thirty-four in the past.
"What really strikes me about Liam is that he grew up and played not far from here, he understands this area," continued Canoville.
"When youngsters see someone like Liam managing the team they support, a person who looks like them, from a similar background, who comes from a household that champions what's right… it is impactful and shows them the path is there.
"Indeed, it is a huge step for the club, for the capital, for every young person dreaming big.
"However, currently? We must support Rosenior, give him what he needs, and let the man get on with the job."
Dutch legend Ruud Gullit was appointed the Blues' head coach in 1996 and became the top flight's inaugural black head coach.
A dozen years on, in 2008, Paul Ince became the first English black manager in the top flight after taking charge at Blackburn Rovers.
West Ham manager Nuno Espirito Santo currently stands as the sole additional current top flight gaffer of colour.
The scarcity of managers of colour across the English game is matched by an absence of diversity in the boardroom.
According to a BFP 2023's study, 43% of top-flight footballers are from black backgrounds.
Yet, research by the equality organization revealed only 3.2 percent of board and senior leadership management teams at 17 of 20 Premier League clubs are held by people from ethnically diverse backgrounds.
Regarding senior coaching level, according to figures from 11 clubs, the figure is 2%.
For all coaching roles – including senior roles – from the same eleven clubs, the figure is just five percent.
"He has undoubtedly broken barriers by virtue of his appointment as a Chelsea head coach, and as an organization, we hope to witness more such appointments," stated Kick It Out CEO Samuel Okafor.
"It is acknowledged there is loads of ability that exists in the ethnic minority groups... aspiring coaches want the opportunity to show their capabilities. We need to continue to striving to dismantle those obstacles down."
Additionally, the new appointee is set to become the fourth permanent British managers presently managing in the top flight – alongside Sean Dyche, Eddie Howe as well as Scott Parker – a number that lags behind Europe's remaining major divisions in terms of national representation.
16 out of twenty first division managers in Serie A are from Italy, Eleven of the 20 are Spanish, 12 in the Bundesliga in Germany while 10 of the 18 are French.
The present Chelsea interim boss Calum McFarlane commented: "I'm sure all aspiring British coaches from an academy background will be, in some way no matter who you support, supporting Liam.
"It's truly inspirational to up-and-coming British coaches in the system to witness someone land such a role with that profile and everyone hopes he will be highly successful."
Rosenior is now the London club's second-ever African heritage manager after Ruud Gullit.
Leroy Rosenior, Liam's father, played for clubs such as Fulham, the Hammers and Queens Park Rangers, and his managerial career peaked with a brief spell at the third-tier club Brentford FC back in 2006.
In 2019, he was awarded an MBE in the Honours List for his services to tackling inequality within the sport and wider society.
After Liam retired from playing he followed his father's footsteps. He began penning articles for a national newspaper, where in 2017 he addressed the under-representation among managers. He highlighted that ethnicity does not influence coaching skill arguing that roles must be awarded on merit.
He further expressed a point he has often stated: how significant under-representation leads to a failure to understand of players with diverse cultural and ethnic heritage.
During an interview for a football podcast, he explained how his star striker, Emmanuel Emegha, was labelled "hard to manage" or "passionate", noting that he could relate to the Netherlands international of Nigerian descent. The striker is expected to join him in moving from Strasbourg to Chelsea this summer.
In further Guardian columns, Rosenior also admitted to being "ashamed" to hear an unnamed coach utter a homophobic slur. He pledged support for the Rainbow Laces initiative and authored a public message to the former US President while he was in office, accusing him of "blatant" racism.
He has subsequently made his name in the dugout – initially with Hull City, later at Strasbourg – and Wayne Rooney recently stating Rosenior was "among the best coaches I've ever worked with" after their time together at Derby County.
The manager bid his farewells at Strasbourg on Tuesday morning prior to putting pen to paper on a six‑and‑a‑half‑year contract at Chelsea.
The Blues boasted the top flight's pioneering African heritage boss with Gullit as well as the first black captain in Paul Elliott.
Elliott later worked in multiple senior positions, including the Football Association's diversity and inclusion board|
