Juve will transfer to their revamped arena in the summer after two disappointing campaigns in Serie A.
"The football season has definitely finished and unfortunately we are perfectly aware that the results haven't been as expected," he wrote on giorgiochiellini.com.
"One year ago, following the World Cup, I was writing that 2011 would have been characterized by redemption, and until January I strongly believed in our possibilities of achieving important results.
"But the luck then abandoned us and our performances became almost poor, thus nullifying our attempts and hopes to achieve a good position for Europe.
"I understand the disappointment of all fans, because I feel the same. These two years have left their mark.
"Our new home can be the start of a new winning era like those of the recent past.
"I can ensure that a united, compacted group has been created, with technical values to be used as a base to build on for our new season."
