They say you should never go back to a club after a successful spell. Things often aren't the same and it's difficult to live up to high standards that were initially set.
Why potentially besmirch all those lasting memories by making a return?
But every now and then, some people and some scenarios buck the trend. And you can bet that's the view of every Chelsea supporter at the moment, with reports suggesting that club legend Didier Drogba could be set to make a sensational return to Stamford Bridge this summer.
According to reports in France (h/t Alan Smith of The Guardian), Jose Mourinho has offered the veteran forward the chance to rejoin the club on a one-year contract.
It's a deal that would also see the 36-year-old assume a coaching role with the Blues once he retires from the game.
Ahead of Chelsea's Champions League clash against Drogba's Galatasaray last March, the Portuguese boss hinted at a summer move for the player, and reports suggest he’s set to act on those words, per Sky Sports:
I think it has to happen one day. When, I don't know - as a player, as a coach, as an ambassador - next year, in four or five years, in 10 years - I don't know.
But when a person represents so much to a club and when a club represents so much to a person - and that's the case - I think he has to be back one day.
Undoubtedly he is one of the most important players in the history of this club - that is not a doubt. I think all Chelsea supporters we agree with that.
Drogba looked as though he'd made the ultimate contribution in his last-ever appearance for Chelsea, scoring the winning penalty in the Champions League final back in 2012.
And while his departure was certainly one for the purists, there are few Chelsea supporters who'd turn down the prospect of a reunion with one of their greatest-ever players.
That’s because he's a figure who still has plenty to offer as a player—even as Drogba approaches the twilight of his career—and potentially as a coach, too.
Drogba showcased at his previous club Galatasaray, and during the World Cup, that he is a forward still well capable of making a major impression on games. Make no mistake, he is still a formidable opponent for defenders and remains physically indomitable.
For Chelsea, you suspect that the Ivorian would typically be brought off the bench to make an impact late on in games. For a tiring back four, can you imagine how difficult a fresh Drogba would be to contain? You certainly don't envy those faced with that prospect.
Belgian football expert Kristof Terreur is intrigued by the pedigree of Chelsea's potential forward options next season should Drogba make the move:
Aside from his capabilities on the field, Drogba is a man who knows Chelsea inside out and is wholly familiar with the mannerisms and requirements that Mourinho expects from his players.
For young players at the club and those who are new to Chelsea, who better to lead by example and show exactly what it means to don the famous blue shirt?
For the strikers—especially for Romelu Lukaku, a burly young forward stylistically similar to the Ivorian—Drogba would be a fine role model.
He knows exactly what the Premier League is about and knows what’s required to stick the ball in the back of the net on a regular basis, as noted here by Opta:
While Drogba's return would have a host of tangible benefits, it's difficult to escape the romanticism that his blue reunion would fester.
Football is all about those spine-tingling moments, and to see Drogba running out at Stamford Bridge again would be wonderful for those who indulge in the Premier League.
And who knows, perhaps Drogba has a few more key contributions left in him.
You wouldn't put it past a player who shone the brightest in his career in the high-pressure matches, and as Chelsea look set to challenge on all fronts next season, there will be plenty of vital matches in which Drogba can leave his mark.
Anyway, even if his on-field contributions aren't quite as significant, Drogba's potential influence at Chelsea as a coach would be vital to the next generation flourishing.
He's Chelsea to the core and a player who needs to be involved in the club at some level; this potential deal would tick all the boxes.
