As Leeds manager he was criticised for the physical and often negative approach of his teams, though the period was noted for its highly physical football across the country. His resignation as England manager fuelled criticism of him as money-obsessed, and unproved allegations of bribery and financial misconduct also tarnished his reputation. He retired in 1984, but was diagnosed with motor neurone disease in May 1987, which led to his death two years later. He remains a highly popular figure in Leeds, and has a stand named after him at Elland Road as well as a statue outside the ground.
