He is nicknamed Ice Man and Lake (the literal meaning of the abbreviation of his surname Sø)
Born in Copenhagen, Sørensen began playing football with hometown clubs Roskilde KFUM and FC Roskilde before joining Lyngby in 2007. After breaking into the first team, he was awarded with a contract until 2013.
Sørensen officially signed for Juventus on 27 August 2010 after a trial with the Turin-based club in July of the same year. He was originally included as 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 by then-Juventus coach, Luigi Delneri. 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 on 23 October 2010, and 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 the Czech international, Grygera. On the long awaited Derby D'Italia between Juventus F.C and F.C. Internazionale Milano he notably 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, Sørensen had signed an additional 4-year contract with Juventus. During the 2011–12 Serie A season, Sørensen found little space in the Juventus first–team under new head coach, Antonio Conte. He was thus sold on a co-ownership deal to fellow Serie A club, Bologna during the winter transfer market in order to gain regular first–team playing time.
On 17 January 2012, he was officially sent to Bologna in a co-ownership deal for €2.5 million (initially in a cash plus player deal: Saphir Taïder). Despite making just 3 league appearances for his new club during the remainder of 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, after they had renewed the co-ownership agreement with Juventus.
On 20 June 2013, his co-ownership deal with parent club Juventus was renewed once again, and Bologna continued to hold his registration for the 2013–14 Serie A campaign that had ultimately ended in relegation for the Emilia-Romagna–based club after they had finished 19th in the Serie A standings.
Return to Juventus
On 20 June 2014, Sørensen was re–signed on a permanent basis by Juventus after the club announced that an agreement had been reached for the outright purchase of the Danish defender.
In August 2014, Sørensen started training with English side Leeds United ahead of completing a loan move to the club, however the move collapsed after a disagreement between the player's agent and Leeds owner Massimo Cellino and he returned to Juventus.
1. FC Köln
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 were knocked out.
