From 1879 onwards he was sending in match reports to local newspapers. He wrote up the Turton matches under the pen name "Free Critic" and, freely critical of his own performances, contributed regular articles to the Bolton Weekly Journal "Cricket and Football Field".
Bentley was playing for Turton F.C. in September, 1880, when at the invitation of Darwen F.C. the two teams formed the Lancashire County Football Association. Challenges were sent to the Manchester Association, Bolton Wanderers, Cob Wall (Blackburn), Blackburn Rovers, Birch Association, Astley Bridge and Christ Church (Blackburn) Clubs for matches.
A number of Turton players figured in County matches, including John James Bentley, his brother Tom Bentley, H. Brown, W. Forrest, J.J. Greenhalgh, J. Hamer, H. Howarth, James Howarth, W.Mather, T. Scowcroft, C. Tootill, P. Toothill, William Trainer, and J. Waddicor.
Bentley was first team captain in 1881 when Sheffield Wednesday came to Turton for an FA Cup match, soon becoming first secretary and then treasurer of Turton F.C.
In 1882, aged twenty two, he set himself up as an accountant in Acresfield, Bolton. His business thrived, and by 1885 he had given up playing, becoming a collector of income tax and the secretary of Bolton Wanderers. He was described at this time as "bold but extravagant, a genius who lived in the future, inspired by a vision of what football could become".
Between the years 1895 and 1900 John James Bentley was probably the most powerful man English football has ever known.
In 1886 he left his Bolton accountant's office to work in Manchester as Assistant Editor, and later Editor, of "The Athletic News". He became a regular columnist in the Daily Express, Daily Mail and "Football chat", a weekly magazine.
In 1887 William McGregor contacted was John Bentley about the formation of a Football League, because of his influence over Lancashire football. He became a founder committee member of the football league, becoming president on McGregor's retirement in 1894, holding the position until 1910 when he became a life member of the Football League management committee.
After leving Bolton Wanderers, he became the chairman of Manchester United in 1902. Bentley's guidance changed the club from a bankrupt outfit to the power we now know, relocating the team from Clayton to their now world famous base at Old Trafford.
He also became vice-president of the FA.
He remained involved with Manchester United until retiring from club administration, in 1916, due to ill health.
Throughout he maintained contact with Turton FC, and was president of the club in the early years of the 20th Century.
He was very keen on the new Harrow game when it was introduced to Chapeltown. His older brothers Thomas and William joined in with the first games played under the Harrow rules, but John was too young to play until the Association Rules had been introduced.
John married and had three children.
John James Bentley died aged fifty eight, and was buried in St Anne's Churchyard, Chapeltown, in September 1918.
In the words of William McGregor: "In all the years I knew John we never exchanged a wrong word, I was always amazed at his unruffled calm, he made mistakes of course but often because he was too generous, money meant little to him he was a soft touch, especially when it came to former players whose requests he rarely refused, he was a man of real worth blind to the faults of his friends, I can honestly say I have never met a kinder or more easy-going man".
The Turton FC away kit is identical to the Physical Education Uniform (P.E. kit) of Turton High School (now also Media Arts College), Bolton, which is the nearest school to Turton and along with the whole of East Lancashire the victim of the mid 1970's county relocation to Greater Manchester.
The Turton FC pitch played on by John Bentley is now owned by 'The Old Boltonians', the amateur football team asociated with Bolton School. Turton FC now play in Edgworth, a mile or two down the road.
