He signed with Barnsley in June 2023 and was loaned to Port Vale for the second half of the 2023–24 campaign. He was loaned to Scottish club Ross County for the 2024–25 season.

Kacper Mieczysław Łopata was born in Kraków on 27 August 2001.^[2] He grew up in Szczecin before he moved to Bristol with his mother at the age of nine.^[3][4] He attended South Gloucestershire and Stroud College (SGS), where the head of football Dave Hockaday became his sporting mentor, helping to steer him towards playing football rather than handball.^[5] He played for the junior teams of St Vallier City, Southampton, Bristol City, Yeovil Town and Brighton & Hove Albion.^[6]

In October 2018, Łopata signed a two-year contract with Premier League side Brighton & Hove Albion, choosing them ahead of Bristol City.^[3] He helped to mark Mason Greenwood out of a game against Manchester United in the FA Youth Cup, with the assistance of teammate Haydon Roberts.^[7] In August 2019, he joined Whitehawk on loan.^[8] He scored within four minutes of his debut against VCD Athletic, though also gave away a penalty kick and was booked for swearing at the referee.^[7] He went on to make 19 appearances in all competitions for the Isthmian League South East Division side, scoring five goals and impressing manager Jude McDonald with his attitude.^[9][7] In January 2020, following a meeting with manager Dariusz Dudek, Łopata joined Polish I liga side Zagłębie Sosnowiec on loan until the end of the 2019–20 season.^[10][11] On 29 February, he made his professional debut in a 2–0 win over Miedź Legnica.^[12] He was released by Brighton at the end of the 2019–20 season.^[13]

On 25 August 2020, Łopata joined Sheffield United on a three-year contract, where manager Chris Wilder got him to train with the first-team rather than the Academy.^[14][15][16] On 10 August 2021, Slavisa Jokanovic handed him his debut at Bramall Lane and he went on to play the full match in a 1–0 win over Carlisle United in the EFL Cup.^[17] On 28 October, he was loaned to National League side Southend United, initially until January 2022, along with fellow Sheffield United player Zak Brunt.^[18][19] He featured 18 times, keeping four clean sheets, helping Kevin Maher's side to go on a 14-game unbeaten league run.^[20] Faced with injuries, the Blades recalled Łopata on 12 March 2022.^[21] Sheffield United rejected a transfer bid from a Polish club but allowed him a permanent transfer to Southend to find first-team football as manager Paul Heckingbottom said "it became clear he didn't want to be here anymore".^[22]

On 2 September 2022, Łopata joined Southend United permanently for an undisclosed fee, signing a two-year deal with an option for another year.^[20] He made an immediate impact at Roots Hall as Southend went nine league games unbeaten, keeping seven clean sheets. He scored his first goal for the club in a 3–0 win at Barnet.^[23] In March 2023, he terminated his contract with the club, apparently unhappy at how players had been treated over unpaid wages,^[24] a decision supported by The Football Association's Contract Disputes Tribunal.^[25]

On 27 March 2023, Łopata joined Woking on a contract until the end of the 2022–23 season.^[26] Following five appearances for Darren Sarll's Cardinals, including a National League play-off quarter-final defeat to Bromley at the Kingfield Stadium, Łopata announced he would be leaving the club at the end of his contract in June via his Instagram account.^[27][28]

On 6 June 2023, Łopata signed a four-year contract with League One club Barnsley.^[29] He made his debut at Oakwell in a 7–0 win over Port Vale on 5 August.^[30] Bobby Hassell, the club's interim director of football, noted that he "started the season in brilliant form and integrated smoothly into the squad".^[31] However, a clavicle fracture saw him lose his place in Neill Collins's team and he found stiff competition for defensive places upon his return to fitness.^[32]

On 1 February 2024, Łopata joined Port Vale on loan for the remainder of the 2023–24 season.^[33] Manager Andy Crosby and director of football David Flitcroft said that he would strengthen the club's defensive options.^[34] He made his debut at Vale Park in a 1–0 defeat to Leyton Orient on 6 February, earning praise from interim manager Will Ryder for his performance.^[35] However, he could not gain a first-team place under new manager Darren Moore.^[36]
