Sørensen officially signed for Juventus on 27 August 2010 after a trial with the Turin-based club in July. He was originally a member of the Juventus Primavera team for the 2010–11 season, however he was called into the first team midway through the 2010-11 Serie A season. After injuries to Leandro Rinaudo and Zdeněk Grygera that would rule them out for several months, Sørensen was called up to the first team for the first time against Bologna and then again, against Milan. In the next league match, on 7 November 2010, due to the unavailability of center backs Giorgio Chiellini and Nicola Legrottaglie, Sørensen made his first start alongside Leonardo Bonucci in the centre of defense. In that match, The Old Lady defeated Cesena 3–1. In the next match, right back Marco Motta was suspended and Sørensen replaced him against A.S. Roma. From that match onwards Sørensen continued to feature for the club at right back, and even managed to maintain a starting position for much of the second half of the season ahead of Motta and Grygera. On the long awaited Derby D'Italia between Juventus F.C and F.C. Internazionale Milano he played the full ninety minutes and silenced Samuel Eto'o in an astounding performance, in which he also made the assist for the only goal of the game.
On 10 May 2011, Sorensen had signed an additional 4-year contract with Juventus.
On 17 January 2012, he was sent to Bologna in a co-ownership deal for €2.5 million. Despite making just 3 appearances for his new club during the 2011-12 Serie A campaign, the young defender became an integral part of his club's first team throughout the 2012-13 Serie A season. On 20 June 2013, his co-ownership deal with parent club Juventus was renewed, while Bologna will continue to hold his registration for the upcoming campaign.
Sørensen has been capped 4 times for the Danish U17 team, twice against Portugal, and twice against Greece. He also played once for the U18 team in an unofficial friendly (against Bavaria) and against Romania U18 as an unused sub. He was a part of the Danish squad for the UEFA European Under-21 Football Championship, but he did not play in any of the three games in the group phase due to injury, where Denmark was knocked out.
