Mancini took charge of his first training session as Gala boss last night after agreeing to replace Fatih Terim as coach of the Turkish champions following a poor start to the season.
Ahead of the trip to Turin for the Champions League clash with the Old Lady, Mancini has declared that Galatasaray represent a unique challenge, while insisting that he is delighted to be back in management so quickly.
He told Il Corriere dello Sport: "It is a happy coincidence to meet the Bianconeri first and it is a great challenge to prepare for this game in just one day.
"I am happy with the choice I made, as the atmosphere is different here in Istanbul. It's a wonderful and intriguing challenge for me at a big club. I am convinced this was the right choice."
The Turkish giants are still reeling from the disappointment of their opening fixture in this season's Champions League - a 6-1 home defeat at the hands of Real Madrid.
