After a summer of transfer negotiations, the Serbia winger finally made the switch from CSKA Moscow in the final days of the market.
"I am truly happy at Juventus and every day that goes by I realise even more how important this club is," Krasic told Serbian media.
"There is nothing that is left to chance and the first impressions have certainly been positive.
"I like Del Neri's approach, even if I can't say I know his tactics or methods quite yet. I'm making progress with the language and can already more or less make myself understood.
"Juventus are truly one of the biggest clubs in the world and I'm very happy here."
