He's rarely been backward about coming forward, either as a midfielder for Leeds United or a TV pundit in his native Ireland.

So it's perhaps a surprise that Johnny Giles has never got round to telling the full story of his own fascinating life.

Now, though, that curious gap in Leeds's footballing library is about to be plugged with the release of his autobiography.
Giles, who these days uses the first name John, is staying tight-lipped on what, if any secrets, are revealed in the book.
Publishers Hodder & Stoughton have proved more forthcoming, however, saying it is "full of warmth, anecdote, insight and humour".
Born in Dublin in 1940, Giles was snapped up by Manchester United aged just 14 before joining Don Revie's Leeds in 1963.
He went on to play a fiercely-competitive role in the great Revie side of the 1960s and 1970s, collecting medals galore and making more than 500 appearances for the club.
His book gives a detailed account of those Elland Road glory years as well as his post-retirement career as a straight-talking broadcaster with Ireland's RTE television network.
It also covers the libel action he mounted over his portrayal in The Damned Utd, Yorkshire author David Peace's novel about Brian Clough's disastrous 44 days as Leeds manager in 1974.
Giles won an apology from Peace in 2008 after claiming the book wrongly painted him as a key figure in Clough's sacking.
John Giles: A Football Man – My Autobiography is published on November 11, priced 19.99 hardback.
* Giles will be signing copies of his book at Waterstone's in Wakefield's Ridings Shopping Centre from 1pm to 2pm on Monday, November 15.
The following day he will be at Waterstone's on Albion Street in Leeds city centre, again between 1pm and 2pm.
