This is a crucial event which marks a young, black British head coach.'
"He is a top tactician that understands the game intimately, which is the most important thing.
"But, in my role as the Blues' first black footballer, I would be lying to claim this news doesn't move me."
Those are the words expressed by Paul Canoville, the man who earned his groundbreaking debut for the Blues' first team as a substitute in April 1982.
This week, the club appointed Strasbourg manager Rosenior, 41, to be their new head coach after the exit of manager Enzo Maresca.
Strasbourg are within the Todd Boehly and Clearlake Capital-owned ownership group that also controls the London club.
There have been a mere twelve black managers – excluding individuals in interim roles – in England's top flight since its inception 34 in the past.
"One thing that impresses me about Liam is he was raised and played locally, he understands the local fans," continued Canoville.
"Whenever children observe someone like Liam managing the team they support, someone who looks like them, from a similar background, who comes from a household that champions what's right… that's powerful demonstrating that opportunities exist.
"Indeed, it is a huge moment for Chelsea, for the capital, for every young person dreaming big.
"But right now? We must support Rosenior, give him the necessary tools, and let the man do his work."
The iconic Dutchman Ruud Gullit became the Blues' manager in 1996 thereby becoming the Premier League's first African heritage manager.
A dozen years on, in 2008, Paul Ince became the first English black boss in the top flight when he took over Blackburn Rovers.
West Ham manager Nuno Espirito Santo currently stands as the sole additional current Premier League gaffer of colour.
The scarcity of managers of colour throughout English football is matched by an absence of representation at executive level.
According to the Black Footballers Partnership 2023's study, forty-three percent of Premier League players come from black heritage.
Yet, analysis from the equality organization found only 3.2 percent of board and senior leadership management teams across most Premier League clubs are from minority ethnic communities.
Regarding senior coaching level, according to data from 11 clubs, the figure stands at two percent.
Across all coaching positions – including senior roles – from the same 11 clubs, the statistic is five percent.
"He has undoubtedly broken barriers by virtue of him being announced as a the Chelsea manager, and as an organization, we want to see more of that," said Kick It Out CEO Samuel Okafor.
"It is acknowledged there is a wealth of ability present in the ethnic minority communities... aspiring coaches desire the opportunity to demonstrate what they can do. We need to continue to striving to dismantle those obstacles down."
Furthermore, Rosenior is set to become one of only four permanent British head coaches presently managing in the top flight – alongside Sean Dyche, Eddie Howe and Scott Parker – which lags behind the continent's other major leagues in terms of national representation.
Sixteen out of twenty top-flight managers in Serie A are from Italy, Eleven in La Liga in Spain, 12 of the 18 are German while Ten of the 18 are French.
Current Chelsea interim boss Calum McFarlane said: "I have no doubt all aspiring British managers from an academy background will be, in some way no matter who you support, rooting for Liam.
"It is really inspirational for up-and-coming British coaches in the system to see an individual land that job with that profile and we hope he will be really well."
Liam Rosenior becomes the London club's second-ever black manager after Ruud Gullit.
His father, Leroy, Rosenior Sr., had a career with the likes of Fulham, the Hammers as well as Queens Park Rangers, with his coaching stint culminating in a brief stint in charge of the third-tier club Brentford FC in 2006.
In 2019, he received an MBE in the Honours List for his services in combating inequality within the sport and beyond.
When Rosenior Jr hung up his boots he followed his father's footsteps. He began writing articles for a national newspaper, where in 2017 he acknowledged the under-representation of black coaches. He pointed out that ethnicity does not influence coaching skill arguing that opportunities should be given on merit.
He also made the view he would repeat: that vast under-representation results in misunderstandings of players with diverse ethnic and cultural backgrounds.
During an interview for a football podcast, Rosenior highlighted how his leading forward, Emmanuel Emegha, was labelled "hard to manage" or "passionate", but said he could relate to the Netherlands international of Nigerian descent. Emegha is set to follow him with a move from Strasbourg to West London in July.
In further newspaper articles, Rosenior also admitted to being "ashamed" upon hearing an unnamed staff member make a homophobic slur. He pledged support for the Rainbow Laces initiative and authored a public message to Donald Trump while he was in office, condemning his "overt" racism.
He has subsequently made his name as a manager – first at Hull City, then Strasbourg – with Wayne Rooney said this week he was "as good a coach as I've ever worked with" following 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 with the Blues.
The Blues had the Premier League's first African heritage manager in Gullit as well as the first black skipper named Paul Elliott.
Elliott later held several senior positions, among them the FA's equality board|
