There is a new triple world champion, two excellent pieces of batting and a new Premier League manager among those who have enjoyed a good week.
A Spaniard comes under fire at the bridge while a boxer's comeback ends nearly as quickly as it started while a captain's decision is being scrutinised and poor results cost a coach his job.
We take a closer look at the moments which have caused joy and pain across a spectrum of sports. Please leave your thoughts on the form below...
The German formula one driver became only the third driver to win three world titles consecutively, along with Michael Schumacher and Juan Manuel Fangio, when he finished sixth in Sunday's Brazilian Grand Prix.
In a dramatic incident-packed, rain-affected race, Vettel fought back to finish sixth after dropping to last on lap one following a collision.
Rival Fernando Alonso of Ferrari finished second, meaning he needed Vettel to be lower than seventh to claim the World Drivers' Championship.
The South Africa-born batsman endured a summer to forget after England lost the Test series to South Africa while he was dropped for the Third Test after he sent derogatory text messages about his team-mates to the Proteas.
It was only in October when Pietersen apologised to fans, his team-mates and the ECB that he was reinstated, the sorry saga concluded and he was re-integrated into the team.
The experienced right-hander proved why he is one of the world's best with a brilliant 186-run knock in England's first innings as they won the second Test by a 10-wicket margin to level the series in India.
The former Tottenham manager was mulling over a move to Ukraine to coach their national football team when QPR came knocking last week. Mark Hughes' loss was Redknapp's gain.
The ex-Portsmouth boss relishes a new challenge and despite the west Londoners being at the wrong end of the Premier League table he jumped at the chance to make the move to Loftus Road.
Redknapp has an excellent reputation of digging teams out of relegation scraps to escape the drop. Sadly for the 65-year-old he was unable to inspire his new side as they lost 3-1 to Manchester United as he watched from the stands at Old Trafford ahead of taking over.
Francois du Plessis
Making your Test debut is nerve wracking at the best of times. Making your Test debut away to Australia is one of the ultimate tests. However, for one all-rounder it was history making.
South Africa were already staring down the barrel of a defeat even though Francois du Plessis made a half century in the first innings of his debut in Adelaide.
Du Plessis defied the odds and batted all day on Monday (seven hours at the crease) in scoring his unbeaten 110 to almost single-handedly deny the hosts victory - becoming the first South African to score a century and a half-century on Test debut in the process.
One would think the appointment of a manager who had won the UEFA Champions League, FA Cup, Spanish league title twice and the FIFA Club World Cup would please many a football fan - but not Chelsea's supporters.
Blues fans were far from happy with owner Roman Abramovich's decision to remove the popular Roberto Di Matteo from the helm and replace him with the ex-Liverpool, Inter Milan and Valencia tactician, a manager who is seen by the Russian billionaire as the man to get the best out of £50million capture Fernando Torres.
Supporters were calling for Benitez's exit almost before he was appointed and they did little to aid his welcome at Stamford Bridge when chanting Di Matteo's name when he took his place on the bench in Sunday's goalless draw with Manchester City.
Few expected to see the 'Hitman' back in the ring following his devastating second round knockout to Manny Pacquiao in Las Vegas in May 2009, the fight which put the Mancunian into retirement.
In September the former two-weight world champion announced his return to the ring with a bout against an unnamed opponent who later turned out to be Ukrainian Vyacheslav Senchenko.
Hatton had never lost in front of his home fans, a record which ended in dramatic fashion on Saturday night. Despite making weight and looking in great shape, the attempted comeback was halted in the ninth round when a tiring Hatton was caught with a devastating body shot - his last act as a professional boxer.
A week after England came under fire for not kicking their goals as they chased a victory against Australia the captain has been highlighted as they kicked a late penalty against South Africa only to run out of time to seal their comeback.
Trailing 16-12 to the Springboks at Twickenham England were awarded a penalty, although there was less than 120 seconds left in the contest while Robshaw had to spend 30 seconds with Owen Farrell about the decision to go for three points.
The apparent indecision over what to do and the final decision proved costly as England suffered an agonising one-point defeat. Next up for Stuart Lancaster's men are world champions New Zealand.
Continuing the rugby union theme Robinson paid the price with his job on Sunday following Scotland's dismal recent runs of results.
Scotland's stunning 9-6 win over Australia in Australia proved a distant memory as the side follow up defeats to New Zealand and South Africa with a surprise 21-15 loss to Tonga at Pittodrie.
The defeat sent Scotland tumbling to 12th in the IRB world rankings, forcing Robinson, who had been popular with supporters, to call time on his tenure.
