Juventus president Giovanni Cobolli Gigli is convinced midfielder Tiago will prove his value before the end of the season.

"I am convinced that Tiago has class - which has been highlighted by Mauro Camoranesi and he will also convince (coach) Claudio Ranieri," said Cobolli Gigli. "Tiago has probably in some cases not been granted opportunities by coach Ranieri because he is forced to go every time for the three points and has made other selections.

"However, I hope that there are other opportunities so Tiago can prove himself at Juventus."
