The Seasiders winger has emerged as a target for a number of clubs this summer with his father revealing that the Premier League new boys have made their presence felt with an official bid of around £8million.
"Cardiff have come in massively for Thomas and the chairman has accepted their offer," confirmed Ince senior. "I'm not sure what the offer is as I've been away.
"It's a case of when he comes back, we'll sit down and see what we want to do.
"He loves it here and has told me he's in no rush to leave the club.
"I think it's 50/50 at the moment. It's a tricky one for me - ideally you want your son to be playing in the Premier League, but you also want him to be playing for you.
"I wouldn't put my hat on it that he'll be playing in the Premier League this year."
