Ivorian striker Drogba was a free agent following his departure from Turkish outfit Galatasaray at the end of last season and will resume his career back at the club with whom he secured legendary status between 2004-12.
Return of the King
Rumours of a potential return to Stamford Bridge for the three-time Premier League winner had been circulating for some time, and Chelsea fans will no doubt be pleased to see Drogba return to boost Jose Mourinho's forward options for the 2014/15 campaign.
As a known favourite of the Portuguese, Drogba notched 157 goals for the Blues during his eight years in West London, fully justifying the faith shown in him prior to his big-money move from Ligue 1 outfit Marseille.
Perhaps his finest moment for the club came in his final appearance, with Drogba scoring both the dramatic equaliser and subsequent winning penalty that saw Chelsea beat Bayern Munich on their own turf to secure the Champions League trophy back in 2012.
"‘It was an easy decision - I couldn't turn down the opportunity to work with Jose again. Everyone knows the special relationship I have with this club and it has always felt like home to me," Drogba said of his return on the Chelsea website.
"My desire to win is still the same and I look forward to the opportunity to help this team. I am excited for this next chapter of my career."
Now Drogba's return is officially secured, the question Chelsea fans will be asking is just how will this impact upon the future of their existing crop of strikers?
With Demba Ba and Samuel Eto'o having already departed following the arrival of Spanish international Diego Costa from Atletico Madrid, the futures of both Fernando Torres and Romelu Lukaku have been subject to increasing scrutiny.
With regards to the former, such a comeback could either be incredibly positive or may just have sealed his exit.
Given their remarkably similar styles, Mourinho could presumably be looking to use Drogba as a mentor for Lukaku or indeed he could just be set to act as a short-term replacement for the Belgian until Mourinho can successfully identify further potentially world-class recruits.
Drogba's initial one-year contract does not appear to include the option to take up a coaching role under Mourinho, although one certainly wouldn't bet against that becoming a possibility in the future.
