LigTV, the official broadcaster of the Turkish league, announced the deal just before the Galatasaray-Besiktas derby.

Reports say that Drogba will pocket a salary of 6 million euros for the 18 months of his deal as well as a signing on bonus of 4 million.

The former Chelsea striker will also get a bonus of 25,000 euros for each game he plays, up to a maximum of 500,000 euros a year, meaning he could earn 11m (£9.63m) euros over the 18 months.

Eurosport Turkey reports that the "agreement is not official yet but sources say it will be done in the next week."

A spokesperson for the Sports PR Company that represents Drogba said: "They have made a formal bid for him."

It is the second massive deal for the Turkish giants this January with Wesley Sneijder having already signed from Inter Milan.

Drogba had been playing in China with Shanghai Shenhua but his future there was plunged into doubt amid reports of unpaid wages.

Drogba signed a two-and-a-half-year deal reportedly worth around £190,000 per week last June, but the Shanghai-based Oriental Sports Daily said the 34-year-old was owed wages in the wake of a long-running equity row at the club.

Drogba applied for permission in November to leave Shanghai on loan before the January transfer window, but FIFA refused the request.

He then returned to Chelsea to train at his former club in a bid to stay sharp for the African Cup of Nations, where he is currently in action for the Ivory Coast.
