Having spent the past five seasons in India, the Ivorian has been a vital cog and played a stellar role at the heart of Pune's midfield.
He will re-unite with coach Derrick Pereira under whom he played during the latter's four-year stint at Pune FC.
Douhou coincidentally won the Durand Cup with the now defunct Mahindra United in 2008 during his first season in India under the same coach.
The Greens finished a very respectable third in a highly competitive 2013-14 Airtel I-League.

"Douhou is a strong physical player and his experience shall hold us in good stead as the I-League gets increasingly competitive," coach Derrick Pereira said about his latest signing.
