Ronnie Schwartz Nielsen (born 29 August 1989) is a Danish professional footballer who plays as a striker. He has made a total of 27 appearances for various Danish national youth teams, scoring four goals.
Career
AaB
Coming through the youth ranks of AaB, Schwartz signed his first professional contract with the club in January 2006, being described as the future goalscorer for the club. Two years and two first team league appearances later, he signed a new contract that was set to expire in the summer of 2011.
Despite being marked as a talent, for the remainder of his AaB time, he never managed to establish himself as a regular in the starting eleven. When his contract expired, he decided to leave AaB and join Randers in the Danish 1st Division, who had just been relegated the previous season, signing a three-year contract.
Randers
Following a good season in the 1st Division, Randers and Schwartz were yet again promoted to the Danish Superliga, finished only behind Esbjerg fB.
In his first top flight season for Randers, Schwartz became the top goal scorer with a total of 14 league goals, finishing 5th overall in the league top scorer table. Thus Schwartz ended up playing an integral part of the Randers side that finished 3rd in the league and 2nd in the Danish Cup. His good efforts were rewarded with a new contract, that was set to expire in the summer of 2016.
During his stint at Randers, Schwartz was lovingly referred to by fans as Plaffeministeren ("The Minister of Shooting") for his many shots on target from long distance and tight angles. The term Plaffeministeren has since been used about other players, and even in other sports to refer to someone, who scores many goals; often on hard strikes.
Guingamp
On 11 June 2014, Guingamp announced that they had bought Schwartz from Randers FC. He was their third Danish signing in the summer of 2014, after Lars Jacobsen and Jonas Lössl. On 12 August 2016, Guingamp announced that they had terminated Schwartz's contract.
Loan to Brøndby
On 27 July 2015, Schwartz signed a one-season loan deal with Brøndby IF. He made his debut on 30 July in a UEFA Europa League qualifier against Omonia Nicosia as a second half substitute, in a match finishing 0–0. In his first derby against Copenhagen on 27 September, he immediately made an impact in the fourth minute by injuring opposing defender Tom Høgli. After six months at the club, he left halfway through his loan deal after failing to gain a place in the starting lineup of Brøndby.
Loan to Esbjerg
On 29 January 2016, after terminating his loan deal with Brøndby, Schwartz joined Danish club Esbjerg on a six month loan deal.
Waasland-Beveren
On 24 August 2016, free agent Schwartz signed with Belgien club Waasland-Beveren. He reportedly agreed to a two-year contract.
Sarpsborg 08 FF
Schwartz was officially announced at Sarpsborg 08 FF on 22 January 2018, signing a two-year contract with the Norwegian club.
Midtjylland
After a number of impressive performances with Silkeborg IF, including 37 goals in 47 league games, Schwartz was signed by FC Midtjylland in January 2020 on a two-and-a-half year contract.
Charlton Athletic
On 4 January 2021, Schwartz joined Charlton Athletic on a two-and-a-half year deal. In doing so, Schwartz became the club's first signing of the January 2021 transfer window. On 8 January, he made his debut for Charlton as a substitute for Paul Smyth in a 0–2 home league defeat against Accrington Stanley. A few days later, he bagged his first goal for Charlton, scoring the equaliser in a 4-4 draw against Rochdale.
