Mads Bech Sørensen

A defender,[5] Sørensen began his youth career with Østbirk IF, before transferring to the academy at AC Horsens in 2011.[6] After progressing through the youth ranks, he won his maiden call into the first team squad for a 1. division match versus HB Køge on 3 May 2015.[7] At age 16 years, three months and 26 days, Sørensen became Horsens' youngest-ever player when he started in the 1–1 draw and he remained on the pitch until being substituted for Malthe Boesen (the player who had previously held the record) after 75 minutes.[8] He made five further appearances during the remainder of the 2014–15 season and signed a new two-year contract on 9 June 2015.[7][9]

Over the course of the 2015–16 and 2016–17 seasons, Sørensen continued to make a handful of appearances a season, mostly as a substitute, even after Horsens' promotion to the Superliga in 2016.[7] After signing a new three-year contract in May 2016, Sørensen made 10 appearances during the 2016–17 season and scored his first senior goal with a consolation in a 3–1 DBU Pokalen last-16 defeat to AGF Aarhus on 15 March 2017.[10] Sørensen appeared in Horsens' opening three matches of the 2017–18 season and scoring the first league goal of his career in a 4–1 victory over Lyngby on 23 July 2017.[7] Despite that excellent start to the season, he departed the club on 31 July,[5] just two days after his final appearance for the club.[7] In just over two years as a first team player at the CASA Arena, Sørensen made 25 appearances and scored two goals.[7] While a Horsens player, he filled the roles of left back, central defender and left midfield.[5]

On 31 July 2017, Sørensen moved to England to join the B team at Championship club Brentford on a four-year contract for an undisclosed fee.[5] Injuries to first team central defenders John Egan, Andreas Bjelland and Chris Mepham saw Sørensen feature as an unused substitute on five occasions during the 2017–18 season and he was promoted into the first team squad for the 2018–19 season.[7][11] He made his debut for the club with a start in an EFL Cup first round match versus Southend United on 14 August 2018,[12] but was substituted with a dead leg after half an hour of the 4–2 victory.[13] After returning to fitness, a knee injury suffered in October kept him out of action for ​2 ¹⁄₂ months.[14] A season-ending injury suffered by central defender Yoann Barbet in late March 2019 allowed Sørensen to break into the starting lineup and he finished the 2018–19 season with 10 appearances.[12][15]

A knee injury suffered prior to Brentford's first friendly of the 2019–20 pre-season kept Sørensen out until late September 2019.[16][17] He resumed his involvement with the first team squad in November 2019 and made two appearances before signing a new ​3 ¹⁄₂-year contract in January 2020.[18][19] Down the pecking order,[20] Sørensen departed on loan for the remainder of the season on 9 January 2020.[18] The COVID-19 pandemic led to his early return from the loan,[21] but he was ineligible for the remainder of the 2019–20 season.[22]

On 9 January 2020, Sørensen joined League One club AFC Wimbledon on loan until the end of the 2019–20 season.[18] Prior to the season being ended early, he made 9 appearances and helped the Dons to avoid relegation to League Two.[19][21]
