Brescia Born in
Sorengo, Berardi made his debut in a 2–1 victory against
Padova on 14 January. At the end of the
2011–12 season, Berardi gained his second promotion to Serie A after winning the Serie B play-offs by beating
Varese 4–2 on aggregate in the two-legged play-off final.
The following club season in Serie A, despite stiff competition from Italian international
Lorenzo De Silvestri, Berardi made 21 appearances in Serie A during the
2012–13 season. However, after the club appointed
Siniša Mihajlović as head coach in November 2013, Berardi lost his place in the starting lineup and only made five Serie A appearances during the subsequent
2013–14 season.
Leeds United On 19 July 2014,
Leeds United announced that they had signed Berardi to a two-year deal for an undisclosed fee. Club president
Massimo Cellino confirmed that Berardi had taken a wage cut to join Leeds. Berardi made his Leeds debut on 12 August 2014, starting the
League Cup match against
Accrington Stanley, but was sent off for a "mid-air sliding tackle" and received a three-match ban as a result. With regular right back
Sam Byram suspended, Berardi was set to start against
Bradford City on 27 August, but was ruled out after picking up a concussion the day before the game. His full league debut was in a 1–1 draw away at
Birmingham City on 13 September 2014. On 20 September, Berardi received his second red card in just his fourth game, after being sent off in a 3–0 win over local rivals
Huddersfield Town. With regular left back
Charlie Taylor pushed forward into an attacking left wing position, during 2015 Berardi became a regular fixture in the
left-back position for Leeds. Berardi finished the season in strong form at left back, starting 10 of the last 11 games and becoming a fans' favourite for his performances. On 21 September 2015, after becoming a highly popular player with the fans for his consistent displays at both right back or left back positions, Berardi signed a two-year contract extension with the club lasting until 2018. On 21 November, Berardi received another straight red card for Leeds in the 73rd-minute of a 1–0 home defeat to
Rotherham United; after being left with a bloodied nose following an elbow to the face from
Leon Best, Berardi pushed Best to the ground before being restrained by his teammates, with both players receiving a straight red card as a result. The ban was later reduced after appeal due to the severity of the elbow Berardi received from Best, provoking the reaction. After returning from suspension, Berardi suffered a torn ankle ligament on 14 December against
Charlton Athletic which ruled him out for two months. After returning from injury, in April 2016, in the return fixture against Rotherham, Berardi – in similar circumstances to the reverse fixture – suffered a bloodied face/head injury after being elbowed by Rotherham striker
Matt Derbyshire, which resulted in Derbyshire's being given a straight red, albeit in a 2–1 defeat for Leeds. Berardi was nominated for the Leeds United Player of the Year award, alongside Charlie Taylor,
Liam Bridcutt,
Mirco Antenucci and
Lewis Cook, though it was awarded to Taylor, whilst he also finished second in the voting for the
Yorkshire Evening Post Player of the Year award, runner-up to eventual winner Taylor. On 7 August, in the opening fixture of the season against
Queens Park Rangers in a 3–0 defeat, Berardi was substituted early in the first half after picking up a hamstring injury. As a result of the hamstring injury, Berardi was ruled out for around six weeks. On 26 October 2016, he made his return when he started in Leeds' penalty shootout victory against
Norwich City in the League Cup, after a dramatic 2–2 draw in normal time. However upon his return from injury, Berardi was kept out the side due to the impressive form of new right back
Luke Ayling. After an Achilles injury to regular left back Charlie Taylor, on 29 December 2016 against
Aston Villa, Berardi came into the side as a left back for a run of games. Berardi's form at left back managed to keep out the returning Taylor for the remainder of the season. On 6 August 2017, Berardi suffered a dislocated shoulder in the 3–2 victory against
Bolton Wanderers in the first game of the season, and had to be replaced by debutant
Vurnon Anita in the first half. On 8 August, he signed a new three-year contract at the club, keeping him at Leeds until the end of the 2019–20 season. On 30 December 2017, Berardi was named as captain and made his 100th appearance for Leeds in the 1–0 defeat against
Birmingham City. On 7 January 2018, Berardi again captaining Leeds scored his first goal for the club and his first ever professional career goal with a "low, swerving shot" from 25 yards in a 2–1 defeat against
Newport County in the
FA Cup. On 7 April 2018, Berardi who was captaining the side, was sent off for a two footed lunge on
Sunderland's
Callum McManaman, with the sending off being his third red card of the 2017–18 season, Berardi was given a five match ban, missing the final five games of the season. After missing 10 games combined through suspension for the 2017–18 season, Berardi apologised for his poor discipline in an interview with LUTV, stating that "it's not good enough for a senior professional player", adding that he will "stop making mistakes when I die". Ahead of the 2018–19 season under new head coach
Marcelo Bielsa, Berardi was training in a new position as a
centre back, and used during pre-season in his new position. He started the season as first choice centre back alongside
Liam Cooper, keeping
Pontus Jansson on the bench, however Berardi was ruled out for a number of weeks after picking up a knee injury against
Middlesbrough on 31 August. After returning from injury after six weeks out injured, Berardi in only his second game back, picked up a separate serious injury on 24 October 2018 in a 2–0 win against
Ipswich Town after suffering a
hyperextention injury to the
hamstring, which would rule him out for several months. Rob Price, Leeds' Head of Medicine, revealed the seriousness of the injury by revealing Berardi "tore his hamstring completely off the bone". During the
2018–19 season, Berardi played 13 matches across the regular season after an injury hit campaign, Berardi started the Championship semi-final first leg as Leeds went 1–0 up away to
Derby County, but was sent off in the 78th-minute of the second leg for a foul on
Bradley Johnson as Leeds lost 4–2 (4–3 on aggregate). The red card was the seventh of Berardi's Leeds career, equalling
Alan Smith as the most red-carded player in the club's history. Berardi scored only the second goal of his career on 13 August in the
EFL Cup tie against
Salford City to help earn a 3–0 victory. He received his eighth red card for the club against
Millwall on 5 October, at the time making him the most red-carded player in Leeds United history. However, the controversial red card was overturned on appeal on 8 October. After the English professional football season was paused in March 2020 due to the
COVID-19 pandemic, the season was resumed during June, where Berardi earned promotion with Leeds to the
Premier League as
EFL Championship champions for the
2019–20 season. However, Berardi injured his
anterior cruciate ligament in the penultimate game of the season as Leeds defeated Derby County 3–1 on 17 July 2020; the injury was set to rule Berardi out for nine months. Having signed a short extension to remain with Leeds during
Project Restart, Berardi's contract ran out at the end of the 2019–20 season. However, he was allowed to remain at the club's
Thorp Arch training ground while completing his rehabilitation from the ACL injury, and on 16 October 2020 signed a new one-year contract for Leeds' first season back in the
Premier League. On 21 May 2021, it was announced that Leeds would release Berardi at the end of the season. On 23 May 2021, after a 3–1 home win against
West Bromwich Albion, Berardi alongside teammate
Pablo Hernandez officially departed Leeds United, bidding an emotional farewell to their fans after making their final appearances for the club.
Sion On 30 January 2022, Berardi returned to Switzerland, joining
Sion until the end of the 2021–22 season. On 31 May 2023, Berardi announced his retirement from professional football at the age of 34. ==International career==
