Danny Rose believes it would be a "waste of time" to do any coaching badges when he retires because black players are "not given a chance" to become managers.
Rose said earlier this month that he "can't wait to see the back of football" due to a lack of decisive action to tackle racism in the game.
He has expanded on that by explaining his frustrations were due to the fact black footballers are rarely given the opportunity when it comes to senior roles off the pitch.
Citing the example of former England defender Sol Campbell, who took over at Macclesfield in November with the club bottom of Sky Bet League Two, Rose said: "Prime example; why has Sol Campbell had to go to the bottom of League Two to get his first job?"
Tottenham left-back Rose, speaking to Sky Sports, added: "No disrespect to League Two, (but) others are at the top end of the Championship, top end of the Premier League for their first jobs, even national teams.
"If somebody like Sol Campbell, with his resume, who he has played for, what he has won – possibly at the time there may have been an argument that he was England's best centre-half – if he has had to go to the bottom of League Two, which I wouldn't mind doing, and others get to be here, why would I want to do that?
"When I said I wanted to walk away from football, people think I was just talking about the two or three incidents that have happened on the pitch.
"When I said that, I was talking about the lack of black managers in football now, or working upstairs in football clubs.
"People ask me if I want to do my coaching badges. Why? You are not given a chance, so no, I wouldn't be looking forward to doing my badges – it is a waste of time. That is what I meant by I am looking forward to calling it a day when the time is right."
Rose also says he was shocked by the leniency of the punishment doled out to Montenegro after a number of their supporters racially abused England players last month.
Montenegro have been ordered by UEFA to play their European Championship qualifier against Kosovo behind closed doors.
Rose and Callum Hudson-Odoi were targeted by groups of home fans within the Gradski Stadion in Podgorica as the Three Lions won 5-1 on March 25.

Raheem Sterling celebrated his goal in the game in front of the Montenegrin fans, who were heard directing monkey chants to some of England's black players.
UEFA announced on Friday that Montenegro had been ordered to play their June 7 qualifier at home to Kosovo in an empty stadium as a result.
Further charges, carrying fines amounting to 20,000 euros (£17,260), were handed down by the governing body for the setting off of fireworks, throwing objects on to the pitch, crowd disturbances and stairways being blocked.
England defender Rose said: "I don't think it is a harsh enough punishment for someone to learn from in the future, just a one-game ban and 20,000 euros – it's a bit shocking but there is not much I can do now.
"I wouldn't want to go back there, but obviously if I have to play there I will play. It's not on my list of destinations to visit.
"That is not to say the whole country is like that, but I have only been there once and I'm mentally scarred a little bit and I am not in a rush to go back there."
England manager Gareth Southgate was visibly upset about the treatment of his players after the game.
Anti-discrimination charity Kick It Out also criticised the punishment from UEFA.
It said on Twitter: "Ever since England's black players received this shocking abuse we have called for the strongest punishment.
"This decision falls way short of that."
The Football Association added in a statement: "We hope that their next home match being played behind closed doors sends out a message that racism has no place in football or in wider society.
"We will continue to work with the relevant authorities in football to ensure that all players are able to enjoy the game in a discrimination-free environment."
