A week is a long time in sport with exhilarating highs often followed by soul-destroying lows.
Of course, the reverse is also possible, evidenced by the fact that David Moyes (spotted sporting an unfamiliar smile this week) tops our list of success stories, while it's Arsene Wenger reaching for the flak jacket and helmet after a hammering that has left him open to a barrage of criticism.

There have been precious few for David Moyes this season, but the embattled Scotsman enjoyed perhaps his best week since taking the reins at United.
Admittedly it came after the nadir of the Liverpool debacle at Old Trafford, but Moyes has generated himself some goodwill after overseeing a commendable Champions League turnaround against Olympiakos and a pretty resounding away victory over in-form West Ham.
While some of the praise for seeing off an extremely limited Olympiakos outfit went perhaps a touch overboard, the result clearly injected some much-needed belief back into a side that had been given a humiliating dressing down by their fierce rivals from Merseyside.
The renewed sense of confidence was nicely encapsulated by Wayne Rooney's freakishly good opening goal at Upton Park and Moyes and his charges will now head into Tuesday's Manchester derby with something approaching a spring in their step.
While there is always plenty riding on a Real Madrid v Barcelona fixture, the stakes were higher than usual ahead of last weekend's Clasico encounter.
Heading into the game four points behind their eternal enemies from the capital, Barcelona knew that defeat would effectively end their title hopes.
Tata Martino's men looked in grave danger of succumbing midway through the second half of a rambunctious affair as Cristiano Ronaldo dispatched a hotly-disputed penalty to put Real 3-2 to the good.
But Real's talisman would not have the last word on this occasion as Barca counterpart Lionel Messi eclipsed him by completing a decisive hat-trick. The little Argentine converted two spot-kicks of his own, the second with just six minutes remaining, to fire his side to a breathless 4-3 victory that catapults them back into title contention.
Messi now has 21 El Clasico goals, three more than the legendary Alfredo Di Stefano and eight more than Real's current hero, Ronaldo.
It proved a hugely-satisfying weekend for Saracens who not only returned to the top of the Aviva Premiership, but did so playing in front of a world-record crowd at Wembley.
A total of 83,889 fans turned up to watch their 39-15 demolition of London rivals Harlequins - the largest-ever attendance for a club fixture.
The impressive Owen Farrell and Chris Ashton were amongst five try-scorers as Sarries underlined their play-off credentials.
And if their victory was not sweet enough, Sale Sharks ensured it took on extra significance as they turned over Northampton to allow Mark McCall's men to usurp the Saints at the summit.
It took a while but, after five straight defeats, Catalan Dragons finally got their Super League campaign off the ground as they upset the form books to defeat Huddersfield.
Things were beginning to look particularly bleak in the South of France with the Dragons squad even hauled in for crisis talks after making their worst-ever start to a Super League season.
But they came to life against last term's League Leaders' Shield winners and bought under-fire boss Laurent Frayssinous a bit of breathing space with a much-improved display.
Louis Anderson played a starring role with two tries and contagiously committed defensive display, but this was a team effort that suggests the Frenchmen are now ready to start looking upwards.
The 1000th game of his tenure as Arsenal manager and one Wenger will want to wipe from his memory as quickly as possible.
Arsenal's fragile title challenge looked to have been on a life-support machine for several weeks, but Chelsea clinically switched it off with a 6-0 mauling of Wenger's men at Stamford Bridge on Saturday.
Two down inside seven minutes, the North Londoners were already well and truly on the ropes by the time referee Andre Marriner awarded a penalty after Alex Oxlade-Chamberlain dived to push away an Eden Hazard shot that appeared to be heading wide anyway.
But the official would weigh in with a body-blow of his own as he then chose to produce a red card for the offence, although he managed to identify Kieran Gibbs as the culprit instead of Oxlade-Chamberlain despite the latter's admissions of guilt.
Rather predictably a heavy defeat then took on massacre proportions as Jose Mourinho's men ran riot, leaving the Portuguese coach's claims that Wenger was a "specialist in failure" ringing in his French counterpart's ears.
Adam Scott arrived at last week's Arnold Palmer Invitational knowing that victory would almost certainly see him replace Tiger Woods as the world No 1 by the time this season's Masters swings around next month.
His efforts over the first two rounds looked to have made that a racing certainty as he followed a course record 62 with a serene 68 that left him a staggering seven shots clear at the halfway stage.
But the Aussie then invoked the spirit of Lytham as he became increasingly erratic over the closing 36 holes, producing an error-strewn final round of 75 that saw him slip from his seemingly impregnable perch down into a third-placed finish.
But while it was a weekend to forget for Scott, it proved one of great joy for Florida native Matt Every who claimed an emotional first-ever victory on the PGA Tour by holding his nerve to emerge triumphant at an event he used to attend regularly as a starry-eyed youngster.
Juan Martin Del Potro
When Juan Martin Del Potro beat Roger Federer to win the 2009 US Open, the giant Argentine looked to have the tennis world at his feet.
But his progress was halted by an injury to his right wrist that caused him to sit out the entirety of the 2010 season and hindered his game for much of the next also.
The 25-year-old had appeared to have put the problem behind him, reaching the Wimbledon semi-finals last year and re-establishing himself as a fixture inside the world's top 10.
But he has now been struck down by an injury to his left wrist which requires surgery and is likely to end his season before it has begun in earnest.
The issue has even lead some to question his long-term future in the game and the deflated South American confessed: "It is not an easy decision, it is not the happiest moment of my career. I experienced a similar situation and I know how hard it is to be out of the tour."
Stuart Broad will have experienced more enjoyable weeks during his time as an England cricketer.
The country's T20 skipper was already less than impressed at being asked to stay on and play in his side's ICC World Twenty20 opener against New Zealand as lightning spikes crashed down around the ground in Chittagong.
Bowling at the time, his mood was soured further when he was carted for a straight six by Brendon McCullum which ensured the Black Caps got ahead on the D/L run-rate at the end of the fifth over of their innings - just enough to ensure the contest could be declared an 'official game'.
Sure enough heavy rain prevented any further play to confirm defeat and, just to compound Broad's fury, he was subsequently fined 15 percent of his match fee for describing the umpires decision-making as "distinctly average".
