Santa Cruz has been linked with a move to Manchester City in recent weeks.
Ince said: “Roque is not one to rock the boat — if that was the case he would have gone in the summer.
“He’s said he loves it at Blackburn and if there was an issue he would have come to see me.
“He has not done that so I presume he’s happy.
“But we’re only a few weeks away from January and it’s now that all the speculation starts.”
