It represents a crucial event that marks the rise of a young, black English head coach.'
"He is a top tactician who knows the game back to front, which is the crucial factor.
"But, as the Blues' pioneering black footballer, it would be dishonest if I said this news fails to move me."
These were the words of Paul Canoville, who earned his groundbreaking debut for the Blues' first team as a substitute in the spring of 1982.
On Tuesday, the club hired RC Strasbourg boss Rosenior, aged 41, as their next manager following the exit of Enzo Maresca.
The French club is within a multi-club ownership group that also controls Chelsea.
There have been just twelve black managers – excluding individuals holding temporary caretaker roles – in the Premier League since it began thirty-four years ago.
"One thing that impresses me regarding Rosenior is he grew up and played locally, he understands this community," added Canoville.
"When youngsters observe someone like Liam in charge of the team they support, a person they can identify with, from a similar background, who comes from a family that champions equality… it is profound demonstrating the path is there.
"Indeed, it is an enormous step for Chelsea, for London, for every aspiring individual dreaming big.
"However, currently? We must support Rosenior, give him the necessary tools, and let the man do his work."
Dutch legend Ruud Gullit was appointed Chelsea head coach back in the nineties thereby becoming the Premier League's first African heritage head coach.
Twelve years later, in 2008, Paul Ince was appointed as the pioneering English black boss in the top flight when he took over Blackburn Rovers.
The Hammers' boss Nuno Espirito Santo currently stands as the only other present top flight boss from a minority ethnic background.
The lack of ethnic minority managers across English football is matched by an absence of representation in the boardroom.
According to a Black Footballers Partnership 2023's study, 43% of Premier League players are from African or Caribbean heritage.
However, analysis by the equality organization found only 3.2% of board and senior leadership positions across most Premier League clubs are from ethnically diverse backgrounds.
At first-team coaching level, according to data from 11 clubs, the figure is two percent.
For all coaching roles – including head coaches – from those same 11 clubs, the figure is just 5%.
"He's certainly made history in terms of his appointment as a Chelsea manager, and we want to see more of that," stated the chief executive of Kick It Out Samuel Okafor.
"We know that there exists a wealth of talent present within black and underrepresented communities... they want the opportunity to demonstrate what they can do. It is imperative to continue to striving to break those obstacles once and for all."
Additionally, Rosenior will become one of only four full-time English managers presently in the Premier League – joining Sean Dyche, Eddie Howe and Scott Parker – a number that trails the continent's other major divisions regarding national representation.
Sixteen of the 20 top-flight managers in Italy are Italian, Eleven of the 20 in Spain, Twelve in the Bundesliga are German while 10 of the 18 are French.
The present Chelsea caretaker manager Calum McFarlane commented: "I have no doubt all aspiring British coaches with a youth development pedigree will be, in some way regardless of allegiance, supporting Liam.
"It's really motivating to up-and-coming British coaches in the system to see someone land that job with that profile and everyone hopes he does really well."
Rosenior is now the London club's second African heritage manager following in the footsteps of Ruud Gullit.
His father, Leroy, Liam's father, had a career with the likes of Fulham, West Ham and Queens Park Rangers, and his managerial career peaked with a brief 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 the 2019 New Year Honours for services rendered 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 addressed the lack of diversity among managers. He pointed out that race does not influence ability and said opportunities should be given on merit.
He further expressed the view he has often stated: how significant under-representation results in misunderstandings of players with diverse 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", but said he could relate to the Netherlands player with Nigerian parentage. Emegha is set to join him with a move from Strasbourg to West London this summer.
In subsequent newspaper articles, he also confessed he was "embarrassed" to hear a staff member make a discriminatory remark. He vowed support for the Premier League's Rainbow Laces initiative and authored an open letter to the former US President while he was in office, condemning his "overt" racism.
He has subsequently made his name as a manager – first at Hull City, later at Strasbourg – and Wayne Rooney said this week he was "as good a coach as I've ever worked with" following their collaboration with Derby.
Rosenior said goodbye at Strasbourg on Tuesday morning prior to putting pen to paper on a six‑and‑a‑half‑year deal at Chelsea.
The Blues had the top flight's pioneering black boss in Gullit as well as the first black skipper in Paul Elliott.
Elliott has since worked in several executive roles, including the FA's equality board|
