How quickly times can change, and don't Philippe Coutinho, Harry Kane, Branislav Ivanovic and even Eden Hazard just know it.
The quadruplet enjoyed excellent form at times last season and were largely responsible for their teams' respective league finishes, but have each endured difficult starts to the new, crazy campaign.
The fall from grace is a hard pill to swallow, but what exactly has happened to the talented foursome?

Let's start with Liverpool's magician. The Reds have begun the season in unconvincing fashion with two 1-0 wins in their opening two games, followed by a draw away to Arsenal and two successive losses at the hands of West Ham and Manchester United.
And to add insult to injury, Coutinho has found himself in the papers for the wrong reasons of late given his red card against the Hammers, even despite his excellent winner against Stoke earlier this season.
Against Bournemouth at home, he managed to cause quite a stir by being in an offside position and attempting to touch a cross that was eventually slotted home by Christian Benteke - an infringement that should have been given offside given the new rules.
And most recently, he was sent off for a silly tackle on Dimitri Payet and paid the price of a red card, missing his side's crunch match with United over the weekend as a result, condemning what has been an indifferent start for the Brazilian.
Next in suspect is PFA Young Player of the Year Kane. The Tottenham man hit 30 goals in all competitions last year and many tipped him to replicate such a season for both club and country.
The frontman, though, has struggled for goals, failing to score in Spurs' opening four games. He hasn't lost all goalscoring form given his two goals during the international break, but that ultimately counts for very little unless he's able to take confidence and implement it into his domestic campaign.
Formally known as Chelsea's Mr. Dependable, Ivanovic's poor start to the new season has been largely responsible for the Blues falling 11 points behind league leaders Manchester City.
Wingers are lining up for a chance to have a go at the vulnerable and out-of-form right-back, but it isn't all his fault, of course - those in front of him have failed to provide sufficient cover - but it might be time for the Serbian to be replaced.
Mourinho, though, would be reluctant to take his vice captain out of the team, but as shown by the dropping of John Terry recently, the Portuguese might not have any choice but to bring in summer signing Baba Rahman to replace the 30-year-old.
Possibly the biggest surprise on this list is the Belgian Hazard, who by his normally high standards has performed woefully this season.
A player who last season took the Premier League by storm, playing a key role in Chelsea's league success and won the PFA Player of the Year, the 24-year-old has failed to show any kind of form that made many liken him to Cristiano Ronaldo and Lionel Messi.
His start has been quite passive for someone of his immense talent who can go past any player at any given moment and shoot comfortably with both feet. He was the reason why Chelsea won a lot of games last year and this season he just hasn't got going yet.
The arrival of Pedro will ease the burden of being the main creator and finisher of the team, but Chelsea need Hazard and they need him soon. Once he's back, good luck trying to stop him.
