Tiago has apologised to Juventus for admitting he wanted to quit the club in the Portuguese press.
"What was said in the interview is regrettable," he explained. "He wasn't playing and felt that he had been banished to the periphery at Juve.
"Now it's different and as the days go by his desire to keep wearing the Bianconeri shirt increases.
"He has realised that his boss Claudio Ranieri values him, but clearly he needs everyone's support if he is to stay in Turin and so I will talk to the directors."
