The 20-year-old centre-back admits that he is in a period of adjustment as he gets used to life in Turin with the Serie A giants
Matthijs de Ligt has admitted that the sense of invincibility that he enjoyed at Ajax has disappeared since he moved to Juventus in the summer.
The 20-year-old centre-back became a target for the gameâ€™s biggest clubs last season with a series of sparkling performances for the Amsterdam side, who reached the Champions League semi-finals and came within seconds of reaching the showpiece before late heartbreak against Tottenham.
Nevertheless, De Ligt was the subject of a bidding war, with Barcelona and Paris Saint-Germain among the teams ultimately beaten off for him by Juventus, who paid â‚¬85 million (Â£74m/$94m) including bonuses to prise him from his homeland.
Since moving to Italy, however, the young defender has struggled to show the same form that he displayed at his hometown side.
â€œAt Ajax, I felt invincible, today itâ€™s different,â€ he told Fox Sports. â€œBut I think itâ€™s normal because everything is new for me. Iâ€™m progressing and Iâ€™m not worried.
â€œI donâ€™t know myself why Iâ€™m not playing as well as Iâ€™d like. All I can do is continue to work, to do my best and to try to learn from my team-mates.
â€œI play and thatâ€™s the main thing because, in the end, Iâ€™m sure that everything will go well and this season will be positive.â€
There were rumours earlier in the month that Juve boss Maurizio Sarri had put him on a carb-free diet in a bid to control his weight, and once again the Netherlands star laughed off such reports.
â€œItâ€™s not a physical problem,â€ he said.
De Ligt has played seven times for Juve since moving to Turin in the summer, playing the duration of all but two of the clubâ€™s games.
Despite worries over his form, Juventus have moved into their familiar position at the summit of Serie A thanks to a 2-1 victory over Inter before the international break. Moreover, they have made a satisfactory start in the Champions League, picking up four points from a trip to Atletico Madrid and a home game against Bayer Leverkusen, who they defeated 3-0 on October 1.
Juve return to action on Saturday with a home match against Bologna before hosting Lokomotiv Moscow in the Champions League.
