Reports in Italy this week suggested a £4 million deal was on the verge of completion with Rovers.
"At the moment I've only read and heard of these things and up till now there's been nothing official," the 27 year old told setantasports.com.
"I haven't met him (Ince). Nothing's been planned," said Grella.
"Tomorrow I should be back in Italy so until I find out any other information I'm a Torino player."
However, the Australian is not against a move to the Premier League.
"Yes, a move to England would interest me," added Grella.
"I think English football at the moment has taken over, it's improved so much, it's full of world champions and it's something that, having been 10 years in Italy, interests me."
