Kjell Knops

Knops trained with former club MVV, before taking a trial at Eerste Divisie side Helmond Sport, signing a one-year contract with Helmond on 23 August 2018. He faced competition for the left-sided centre-back spot from Joeri Poelmans, Ron Janzen and Nick de Louw. He made 17 appearances across the 2018–19 campaign as Sport finished bottom of the table but were reprieved from relegation due to a league restructuring.

In June 2016, he signed a two-year contract with EFL League One club Port Vale. He was manager Bruno Ribeiro's first signing for the club, and Knops said that he wanted to come to Vale Park because of Ribeiro's attractive style of football. He began the 2016–17 season playing at left-back after injuries to Kiko and Adam Yates. He adapted well to the role and forged an effective partnership with left-winger Jerome Thomas, and remained the "Valiants" first choice left-back despite the signing of Sam Hart and Kiko's recovery from injury. He continued to hold down a first team place despite the arrival of specialist left-back Scott Tanser in the January transfer window. However, he snapped his knee during a 3–0 defeat to Rochdale at Spotland Stadium on 4 April, and was ruled out of action for nine months. His knee also became infected, forcing him to spend three weeks in hospital. Speaking in June 2017, manager Michael Brown revealed that the infection had returned to the area and further surgery was required, which would keep him ruled out for the 2017–18 season. In May 2018 he was released upon the expiry of his contract by new manager Neil Aspin. However he stayed on to train with the club in order to try and win a new contract. He returned to Holland to find a new club at the end of June, citing family reasons.

Knops returned to professional football when he signed with René Trost's MVV in the Eerste Divisie (second tier) for the 2011–12 campaign. He scored his first goal for the club in a 3–2 win over Telstar at the Rabobank IJmond Stadion on 21 October. Four days later he received the first red card of his career after he committed a professional foul in a 1–0 defeat to Achilles '29 in the KNVB Cup. He was sent off for the second and final time of his MVV career on 20 January, afetr receiving two yellow cards in a 2–2 draw with Helmond Sport at the Stadion De Braak. He featured in a total of 36 games, including both legs of the play-off round one defeat to Cambuur, after the club qualified for the play-offs with an eighth-place finish. He again played 36 matches in the 2012–13 season as MVV finished in fifth place to go straight into the second round of the play-offs, where they were beaten 4–1 by FC Volendam; he later said this was the greatest achievement of his career. He scored his second and final goal for the club on 1 March 2013, in a 2–1 defeat to FC Emmen at De Geusselt. He signed a new two-year contract in June 2013. MVV finished in 11th place in the 2013–14 campaign, with Knops featuring only 26 times as he spent two months out with a knee injury. He made 29 appearances in the 2014–15 campaign, as MVV again finished in 11th spot, and was appointed as club captain. He played 40 games in the 2015–16 season as MVV finished in tenth place, before dropping out of the play-offs at the first round following defeat to FC Volendam. His contract with the club ended on 31 March 2016.

Knops enjoys playing tennis in his spare time. He speaks Dutch, German, and English. He worked as a salesman from August 2010 to June 2011, and as an account manager at the Dutch Calendar Factory from March 2012 to July 2013; he has attended Zuyd University of Applied Sciences.

He began his professional career with Roda JC Kerkrade in 2008, before dropping into amateur football with EVV for the 2010–11 season. He then moved up to the Eerste Divisie for a five-year spell at MVV, who he also captained. He left the Netherlands and travelled to England to join Port Vale in June 2016. He spent two years with the club, but missed the entirety of the 2017–18 season due to injury. He returned to the Netherlands and signed with Helmond Sport in August 2018 and then joined Groene Ster in June 2019.

Knops spent his youth with Roda JC Kerkrade. He made his first team debut in professional football in the Eredivisie (first tier) as a late substitute for Marcel de Jong in a 3–0 win over NEC at the Parkstad Limburg Stadion on 15 November 2008. This would prove his only appearance for the club, and he was one of 11 players released by general manager Martin van Geel in April 2010. He played on trial at RKC Waalwijk in May 2010. He then spent the 2010–11 season in the Topklasse (third tier) with amateur side EVV, and made 28 league and cup appearances as the club posted a ninth-place finish in the Sunday league. He scored two goals for the club, in victories over AFC and Dijkse Boys.
