Karsdorp training for
Feyenoord, as he left the training field following a groin injury while the club's coach looked on.
Born in
Schoonhoven, Netherlands, Karsdorp started at
VV Schoonhoven [
nl], as his father, Fred, worked there as a trainer.[3][4] Karsdorp was then scouted by
Feyenoord and as a result of joining the club and his parents’ divorce, he and his father moved to Bergambacht.[4] However, Karsdorp revealed that: "When things did not go so well for me at school in my youth, my father coordinated with Feyenoord that I was not allowed to play football anymore. Only when things got better at school. I was allowed to come back to the training. That has been a good lesson in my development."[3][4][5] Following his improved behaviour at school, he re–joined VV Schoonhoven and stayed there for six months before re-joining Feyenoord.[4] Karsdorp became a youth exponent from the
Feyenoord Academy.[4] He started out, playing in the midfield position before playing in the right–back position.[6] In December 2013, Karsdorp signed his first professional contract with the club, keeping him until 2015.[7]

HNK Rijeka on 23 October 2014, Karsdorp was at fault when he and
Matthew Steenvoorden were completely misjudged, leading
Andrej Kramarić to score, as the club lost 3–1.[11] Shortly after, Karsdorp signed a contract extension with Feyenoord, keeping him until 2018.[12] Since the start of the season, Karsdorp found himself placed on the substitute bench, due to a competition from fellow right–backs,
Khalid Boulahrouz and
Luke Wilkshire.[13]
By February, he became a first team regular in the right–back position following the absence of Boulahrouz and Wilkshire.[14] In a match against
PSV Eindhoven on 22 March 2015, Karsdorp set up the club's first goal of the game for
Anass Achahbar, who scored twice, in a 2–1.[15] He then set up Feyenoord's first goal of the game, in a 4–1 loss against

SC Cambuur and Vitesse.[22] Karsdorp set up three goals in three matches between 13 September 2015 and 27 September 2015 against
Willem II,
Roda JC and PEC Zwolle.[23] However, he suffered a groin injury while training that saw him sidelined for a month.[24] While on the sidelines, Karsdorp signed a contract extension with Feyenoord, keeping him until 2020 on 23 October 2015.[25] He didn't make his return to the first team until on 1 November 2015 against
ADO Den Haag, starting a match and played 74 minutes before being substituted, in a 1–0 loss.[26] His assist form continued when Karsdorp set up the club's fourth goal of the game, in a 5–0 win against
FC Twente on 22 November 2015 and this was followed up by setting up two goals, in a 4–2 win against
SBV Excelsior.[27]
Following his return from injury, he continued to regain his first team place, playing in the right–back position.[28] However in mid–February, Karsdorp suffered a groin injury that kept him out for two matches.[29] It wasn't until on 28 February 2016 when he returned to the starting line–up, in a 2–1 win against Utrecht.[30] Karsdorp then set up two goals, in a 2–0 win against Vitesse on 13 March 2016.[31] Since returning from injury, he continued to regain his first team place, playing in the right–back position and helped Feyenoord not only win the

in the final, but also helped Feyenoord finish third place in the league after beating Willem II 1–0 on 1 May 2016.[32] At the end of the 2015–16 season, Karsdorp went on make thirty–five appearances in all competitions.
2016–17
At the start of the 2016–17 season, Karsdorp started the whole game in the right–back position, as Feyenoord lost 1–0 against
PSV Eindhoven in the
Johan Cruyff Shield.[33] He helped the club keep three consecutive clean sheets in the first three league matches against
Groningen, Twente and
Heracles.[34] Since the start of the 2016–17 season, Karsdorp continued to regain his first team place, playing in the right–back position.[35] It wasn't until on 30 October 2016 when he scored his first goal for the club, in a 2–2 draw against Heerenveen.[36]

Roma
On 28 June 2017, Karsdorp signed with
Roma on a five-year deal for a fee of €14 million with various performance-related clauses worth up to €5 million in additional payments. With the transfer, he became Feyenoord's most expensive outgoing player in history.[41]
However, Karsdorp suffered a knee injury that saw him sidelined at the start of the 2017–18 season.[42] After returning to the substitute bench in October, he made his Roma debut, starting a match and played 82 minutes before being substituted, in a 1–0 win against
Crotone on 25 October 2017.[43] But his return was short–lived when Karsdorp suffered a knee injury during the match against Crotone and was sidelined for the 2017–18 season.[44] This turns out to be his only appearance for the club.
Ahead of the 2018–19 season, Karsdorp switched number shirt from twenty–six to two.[45] He then returned to the first team and didn't make his first appearance of the season until on 31 August 2018, starting a match and played 77 minutes before being substituted, in a 2–1 loss against
A.C. Milan.[46] But Karsdorp found himself behind the pecking order in the first team, resulting in him being placed on the substitute bench, as well as, his own injury concern.[47] He then started in the next five matches, playing in the right–back position between 14 January 2019 and 8 February 2019.[48] Following another injury sustained, Karsdorp found his playing time, mostly from the substitute bench, as he continued to fight for his first team place, as well as, his own injury concern for the rest of the 2018–19 season.[49] At the end of the 2018–19 season, he went on to make fourteen appearances in all competitions.
Return to Feyenoord (loan)
On 7 August 2019, Karsdorp returned to Feyenoord on a loan for the remainder of the season.[50] Upon joining the club, he said: "I didn't play much football for two years, everyone knows that. It was often said that I was injured, sometimes that was not the case, but I feel fit now."[51]
Karsdorp's first game after signing for Feyenoord on loan came in the opening game of the season, in a 1–1 draw against Heerenveen.[52] Karsdorp then played in both legs against
Hapoel Be'er Sheva and set up two goals in the second leg, as he helped the club win 6–0 on aggregate to reach UEFA Europa League Group Stage.[53] It wasn't until on 15 September 2019 when Karsdorp scored his first goal for the club, in a 3–2 win against ADO Den Haag.[54] After missing one match, he returned to the starting line–up against FC Twente on 29 September 2019 and set up Feyenoord's first goal of the game, in a 5–1 win.[55] This was followed up by scoring his second goal of the season, in a 2–0 win against

I am happy with the two victories and I don't want to be involved with the Orange at all. I only played four games here, before that. Fifteen matches in 100 weeks. Look, if I have played twenty games, delivered ten assists and scored five goals, you can ask me whether the Orange will come back into the picture. I have consciously returned to Feyenoord. You just know that if you play here every week and you are doing well that opportunities arise".[83]
In June 2018, Karsdorp married his long term–girlfriend, the South American model Astrid Lentini.[85][86] In addition to Dutch, he speaks English and is learning Italian. His wife, Astrid, who is of Italian origin, helps interpret the language for him.[87] The couple has two sons.[86]
