Courtney Meppen-Walter, 18, was arrested last September after his silver Elegance CDI car was travelling nearly twice the speed limit when it ploughed into a red Nissan Micra pulling out of a side street.
The impact in Cheetham Hill, Manchester claimed the lives of Kulwant Singh, 32, who was driving the Micra and 37-year old sister Ravel Kaur who was a front seat passenger.
Mrs Kaur's two sons Amjid and Parveen, who are 16 and 17-years-old, were sat in the back and were left fighting for life with serious injuries and had to be cut free from the mangled wreckage. They have since made a good recovery.
Police initially investigated whether Meppen-Walter from Blackley, Manchester was racing a friend in a VW Golf as both cars appeared to be accelerating and slowing down apparently to avoid speed cameras.
Today the £1,000-a-week defender who has been at City since 2003 and has represented England at under-17 level pleaded guilty to two offences of causing death by careless or inconsiderate driving.
He asked to be dealt with at Manchester magistrates court where jail terms cannot exceed six months - but the bench instead sent to him to be dealt with by a judge at crown court as they ruled the offence was too serious and bordered on dangerous driving.
Meppen Walker was given an interim driving ban pending sentencing next month.
The tragedy occurred at about 10.15pm on Saturday September 1 last year on Bury New Road at its junction with Sherborne Street.
