On 25 July 2014, Chelsea announced on their official website that Drogba completed his return to the club on a free transfer, and signed a one-year contract.
Speaking on his move back to the club, Drogba said:
It was an easy decision.
I couldn't turn down the opportunity to work with José Mourinho again.
Everyone knows the special relationship I have with this club and it has always felt like home to me.

 Mourinho also commented on the transfer, saying: "He's coming because he's one of the best strikers in Europe.
I know his personality very well and I know if he comes back he's not protected by history or what he's done for this club previously.
He is coming with the mentality to make more history."
On 28 July 2014, Chelsea announced that Drogba would wear the number 15 shirt which he wore when he first signed for the club in 2004.
Mohamed Salah, who wore the number during the 2013–14 season, took over the number 17 shirt vacated by Eden Hazard.
On 15 August, however, it was announced that Drogba had been given back the number 11 shirt he previously wore at the club, with its previous occupant Oscar taking over the number 8 jersey vacated by Frank Lampard.

Drogba made his Premier League return for Chelsea in a 3–1 win away to Burnley, replacing winger Eden Hazard in the 84th minute at Turf Moor on 18 August 2014.
On 17 September he made the first start of his second spell, in a 1–1 home draw against Schalke 04 in Chelsea's first game of the Champions League group stage.
He scored his first goal in his second spell at Stamford Bridge on 21 October, converting a penalty kick in a 6–0 win over Maribor in the Champions League.
Five days later, with Chelsea's attack limited by injuries to Diego Costa and Loïc Rémy, Drogba started against Manchester United at Old Trafford, making his 350th appearance for the club.
Early in the second-half, he headed in the first Premier League goal of his second spell although Robin van Persie equalised in added time.
He scored his 50th goal in European football against Schalke 04.

On 24 May 2015, Drogba announced that Chelsea's final game of the season against Sunderland would be his last as a Chelsea player.
He started the game as captain and was substituted with injury after half an hour, being carried off by his teammates in an eventual 3–1 win.
