Harry Redknapp is currently on trial on charges of tax evasion, relating to two alleged payments totalling £183,000 made to foreign bank accounts during his time as manager of Portsmouth.
The current Tottenham boss, who is hotly tipped to take over as England manager in the summer when Fabio Capello moves on, is far from the first sporting figure to have run-ins with the tax authorities.
Some have been found guilty, while others have walked away from the charges. Here's our pick of some of the stories.

The German tennis star had a 10-year battle with German tax authorities over his claim that he was living in Monaco during the early 1990s rather than an apartment in Munich. An investigation that took nearly a decade eventually came to court in 2002, at which point Becker suddenly admitted everything and agreed to pay three million euros in back taxes.
Becker later blamed his "great fear" of the prosecutors for ending his career: "This tax issue hasn't let me sleep soundly since the first search of my home. It is telling that I was not able to win a tournament after that," he said.
"I couldn't live like that any more, much less play tennis. Tennis is a psychological sport. I quit the game then, because I couldn't continue like that."
Jesse Owens - GUILTY
One of the greatest athletes of all time - who once smashed four world records in 45 minutes and made Hitler's Germany look ridiculous at the 1936 Berlin Olympics - eventually cultivated a successful career in motivational speaking once his athletic career was over.
Not that you'd have known it from his tax returns: Owen was convicted of tax evasion after failing to file tax returns between 1954 and 1962, and was fined $3,000 (roughly $23,000 in today's terms) in addition to paying up his back taxes.
The world's most famous boxing promoter has probably spent more of his life in court than most barristers, having faced cases for everything from insurance fraud to murder - twice. (On the first of those occasions his plea of self-defence was accepted; on the second - in which he kicked a man who owed him $600 to death - he was convicted of second degree murder but later had the conviction downgraded to manslaughter.)
He has also faced tax charges on several occasions: in 1985 he was found not guilty after evidence in an earlier alleged tax evasion from 1974 was ruled inadmissible, and then again in 1991 when a judge declared a mis-trial after one of the jurors admitted reading up on potential sentences.
King has also been sued numerous times by boxers - among them Muhammad Ali, Mike Tyson and Lennox Lewis - for allegedly withholding millions of dollars from them.
O.J. Simpson - GUILTY
Yes, the Juice's tax bills are probably the least of the issues that have dogged his life, but O.J. Simpson was caught owing the US's Internal Revenue Service somewhere between $600,000 and $700,000 in back taxes in 1997. Simpson admitted he owed the government money in 1997 while talking with reporters before a "debtor's examination" in the wrongful-death civil lawsuit against him. "I'm sure I owe them money," Simpson said as he arrived at the back entrance of the courthouse, "but I don't think I broke the law ... you can owe money without breaking the law."
Simpson was found not guilty of the 1994 murder of his ex-wife Nicole and her friend Ronald Goldman, but he was found liable for their deaths by a civil court, and ordered to pay $33.5m in damages.
Baseball legend Pete Rose enjoyed a glittering career at the top of his sport, and still holds the record for the most hits in a career. But he has been dogged by controversy, and he spent five months in prison in 1990 for failing to pay tax on sales of autographs and memorabilia, as well as his horse racing winnings. In addition to his prison stint he was also fined $50,000, ordered to pay $366,041 in back taxes and interest, and had to do 1,000 hours of community service.
As a manager Rose was also investigated for betting on games involving his team, the Cincinnati Reds, with some alleging that he bet against his men - something he vehemently denies.
"I bet on my team every night. I didn't bet on my team four nights a week. I bet on my team to win every night because I loved my team, I believed in my team," he said. "I did everything in my power every night to win that game."
He didn't do everything in his power to mend his ways, however, and in 2004 was slapped with a further $1m bill for unpaid taxes.
Steffi Graf - INNOCENT
In 1995 the German superstar was accused by authorities of evading tax on $6.55m of her earnings in the early years of her career. She successfully claimed that the improprieties were actually committed by her father, Peter, who was convicted and served just over two years in jail for the crime. A case against Graf herself was dropped when she agreed to pay 1.3m Marks to the government.
Unlike Becker (above), Graf's career never missed a beat while all this was going on: she won three Grand Slam singles titles in both 1995 and 1996.
The former Chelsea manager claimed to be a resident of Belgium from 2002 to 2003, therefore sparing himself a 1.4m euro tax bill. But a Dutch court ruled that he had not spent enough time at his house in Belgium to be able to nominate it as his primary residence. He was convicted of tax fraud, with the court reaching the conclusion that "Hiddink deliberately submitted an incomplete and incorrect tax declaration over 2003".
The prosecutors - who had dismissed his Belgian claim as a "joke"- demanded a 10-month prison sentence, but Hiddink was let off with a 45,000 euro fine and a six-month suspended sentence.
Diego Maradona - STILL UNDER INVESTIGATION
Italian authorities finally started catching up with the Argentine superstar in 2009 over his unpaid tax bill from his 1984-1991 spell at Napoli. The original debt was 13m euros, but that has swollen to 37m euros with interest and penalties.
So far the authories have auctioned off a couple of confiscated watches and a pair of diamond earrings to try to recoup the debt, raising 42,000 euros. But late last year the investigation was reportedly restarted from scratch after Maradona's lawyer Angelo Pisani successfully argued that his man had been sent the wrong tax return form back in 1988.
Italian tax authorities will keep on plugging away, though: they are rampant when it comes to trying to investigate celebrities' peccadilloes and have investigated the likes of Fabio Capello and Valentino Rossi.
Capello, incidentally, settled a 2004 dispute with Italian authorities when he admitted that he didn't even know the address of the Swiss house that he had claimed as his primary residence.
The legendary jockey was convicted in 1987 of avoiding tax on £3.25m of income, after diverting funds from both riding and bloodstock through trading via bank accounts in Switzerland, the Cayman Islands, Singapore and the Bahamas between 1970 and 1985.
Piggott, 51 and having retired to become a trainer at the time of his conviction, served one year of his three year sentence. He came out and returned to riding in 1990, winning his first race within 10 days of his comeback and even going on to add to his list of Classic wins as he took the 2000 Guineas in 1992.
George Reynolds - GUILTY
The former Darlington FC chairman came into football club ownership after eschewing an earlier life of crime which saw him serve time for safe-cracking, handling explosives and burglary.
After his release from jail, however, he seemed to get his life back on track as he built a £260m fortune from businesses such as kitchen installations.
But it seems the old habits just wouldn't die: he was stopped in 2004 with £500,000 in cash in the boot of his car. Though he was acquitted of money laundering he was convicted of tax evasion, and served 14 months of a three-year sentence.
His five-year spell as chief of Darlington was equally controversial: he started well, building a new stadium, but eventually left the club in administration in January 2004.
Having re-entered administration recently, the club were saved from liquidation at the 11th hour after a rescue group pledged £50,000 to ensure their survival for the next three games.
