The Spain striker laughed off question marks over his readiness for the season ahead at his official unveiling with the Italian champions
The Spain striker has signed a four-year contract with the Turin giants after an unsettling final season with Athletic Bilbao, in which he started only four Liga games due to a dispute with coach Marcelo Bielsa.
But the 28-year-old insists he is physically and mentally ready to spearhead the Juve attack as Antonio Conte's men go in search of more major honours after claiming back-to-back Serie A titles.
"Physically I feel very well," said the Bosman free signing at his official unveiling on Tuesday. "I have worked very hard during my holidays and now I am ready to work even harder in the future.
"Over the last two years I have still done a lot of physical training even when I have played much less. I know Italian football is very difficult, but I am sure I will be able to do well."
The World Cup winner also stressed his delight in joining the Italian champions, explaining that Juve were the sole attraction in his move.
"I decided to come to Italy because this is where Juventus play! I chose to play for Juve because they are a great team, and it is a dream for me to play here. I want to develop as a player and I have chosen the best team with which to do that.
"I have spoken a few times with Antonio Conte and I'm very happy to be able to play under him. Juve played wonderful football last season and deserved to win the Scudetto. Now I want to help the team win and achieve the feat of a third consecutive title. The Champions League, though, is a difficult competition and we must take one step at a time."
Llorente's unveiling comes days after the club confirmed the arrival from Manchester City of Carlos Tevez as Juventus add to an already star-studded squad, and the Spaniard was quick to point out one player in particular he is looking to join forces with.
"I hope that Andrea Pirlo can help me to develop as a player," he said. "I admire champions like Roberto Baggio, Alessandro Del Piero and David Trezeguet too, and the fans' welcome was incredible. They are fantastic. I would like to thank them and say that I am very happy."
The Spain international will wear the No.14 shirt with his new club.
