Early career / Porto

Săpunaru was born in Bucharest and is a product of Național București, joining its youth system at the age of only six. He signed for Rapid București in July 2006, and two years later was sold for €2.5 million to Porto as a replacement for Chelsea-bound José Bosingwa. Săpunaru agreed to a five-year contract,^[2] with the Primeira Liga club owning 50% of the player's economic rights, while Romanian sources indicated the price was actually €6 million plus two players.^[3]

During his debut campaign, Săpunaru was the first-choice right-back as the northerners achieved a double, and scored his first goal in a 1–2 away loss against Nacional for the Taça da Liga.^[4] In early February 2010, he was suspended in Portugal–as his teammate Hulk–following incidents during a 0–1 league defeat at Benfica, so he returned to his country for a five-month loan with former side Rapid;^[5] he did not manage to be played regularly at Porto during that time but, following his return for the 2010–11 season, became a very important first-team unit as they won three major titles, appearing in 40 official games in the process.

On 17 February 2014, Săpunaru was condemned to pay a €90,000 fine for his participation in the assault of two stewards at the Estádio da Luz on 20 December 2009.^[6][7][8]

Spain

On 31 August 2012, Săpunaru signed a one-year contract with La Liga club Real Zaragoza.^[9] He made his official debut on 16 September, playing the full 90 minutes in a 0–2 loss at Real Sociedad.^[10]

In his first season in Aragon, Săpunaru started but also suffered team relegation. He also entered his name in the competition's history books, after breaking the record for the most bookings in a single campaign (19 yellow cards and one red).^[11]

After initially hesitating because of the requests of his partner,^[12] Săpunaru signed a one-year deal at fellow league team Elche on 25 July 2013.^[13] He totalled only nine appearances in his only campaign and was also sent off twice, while his sole goal opened a 1–2 loss at Valencian Community neighbours Levante on 13 December.^[14]

Elche could not support Săpunaru's €1 million wage demands,^[15] and released him on 21 August 2014.^[16] In October 2015, he took the club to court for the wages remaining in his contract.^[17]

Later career

After four months back at Rapid, Săpunaru signed a season-long deal at Pandurii Târgu Jiu on 6 September 2015, including a clause that he could leave instantly if a foreign club wanted him.^[18] The following 21 July, he put pen to paper to a two-year contract with fellow league side Astra Giurgiu.^[19]

On 1 July 2017, it was announced that Săpunaru signed a two-year deal with Turkish Süper Lig team Kayserispor.^[20] At its expiration, he joined Denizlispor in the same competition,^[21] before returning to his previous employer in January 2020 for the rest of the season. In August, he signed a new one-year deal.^[22]

Săpunaru signed for Rapid for the fourth time on 4 July 2021, joining on a two-year contract at the age of 37.^[23]
